Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains found in AMP-activated protein kinase gamma-like proteins, repeat 1; AMP-activated protein kinase (AMPK) plays multiple roles in the body's overall metabolic balance and response to exercise, nutritional stress, hormonal stimulation, and the glucose-lowering drugs metformin and rosiglitazone. AMPK consists of a catalytic alpha subunit and two non-catalytic subunits, beta and gamma, each with multiple isoforms that form active 1:1:1 heterotrimers. This cd contains 2 tandem repeats of the CBS domains found in the gamma subunits of AMPK. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair. The interface between the two CBS domains forms a cleft that is a potential ligand binding site. The CBS pair coexists with a variety of other functional domains and this has been used to help in its classification here. It has been proposed that the CBS domain may play a regulatory role, although its exact function is unknown. Mutations of conserved residues within this domain are associated with a variety of human hereditary diseases, including congenital myotonia, idiopathic generalized epilepsy, hypercalciuric nephrolithiasis, and classic Bartter syndrome (CLC chloride channel family members), Wolff-Parkinson-White syndrome (gamma 2 subunit of AMP-activated protein kinase), retinitis pigmentosa (IMP dehydrogenase-1), and homocystinuria (cystathionine beta-synthase).

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the ACT domain; The putative Acetoin Utilization Protein (Acub) from Vibrio Cholerae contains a CBS pair domain. The acetoin utilization protein plays a role in growth and sporulation on acetoin or butanediol for use as a carbon source. Acetoin is an important physiological metabolite excreted by many microorganisms. It is used as an external energy store by a number of fermentive bacteria. Acetoin is produced by the decarboxylation of alpha-acetolactate. Once superior carbon sources are exhausted, and the culture enters stationary phase, acetoin can be utilised in order to maintain the culture density. The conversion of acetoin into acetyl-CoA or 2,3-butanediol is catalysed by the acetoin dehydrogenase complex and acetoin reductase/2,3-butanediol dehydrogenase, respectively. Acetoin utilization proteins, acetylpolyamine amidohydrolases, and histone deacetylases are members of an ancient protein superfamily.This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains in the acetoin utilization proteins in bacteria. Acetoin is a product of fermentative metabolism in many prokaryotic and eukaryotic microorganisms. They produce acetoin as an external carbon storage compound and then later reuse it as a carbon and energy source during their stationary phase and sporulation. In addition these CBS domains are associated with a downstream ACT (aspartate kinase/chorismate mutase/TyrA) domain, which is linked to a wide range of metabolic enzymes that are regulated by amino acid concentration. Pairs of ACT domains bind specifically to a particular amino acid leading to regulation of the linked enzyme. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains superfamily; The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair. The interface between the two CBS domains forms a cleft that is a potential ligand binding site. The CBS pair coexists with a variety of other functional domains and this has been used to help in its classification here. It has been proposed that the CBS domain may play a regulatory role, although its exact function is unknown. Mutations of conserved residues within this domain are associated with a variety of human hereditary diseases, including congenital myotonia, idiopathic generalized epilepsy, hypercalciuric nephrolithiasis, and classic Bartter syndrome (CLC chloride channel family members), Wolff-Parkinson-White syndrome (gamma 2 subunit of AMP-activated protein kinase), retinitis pigmentosa (IMP dehydrogenase-1), and homocystinuria (cystathionine beta-synthase).

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the BON (bacterial OsmY and nodulation domain) domain; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the BON (bacterial OsmY and nodulation domain) domain. BON is a putative phospholipid-binding domain found in a family of osmotic shock protection proteins. It is also found in some secretins and a group of potential haemolysins. Its likely function is attachment to phospholipid membranes. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.

CBS pair domain found in Hypoxic Response Protein 1 (HRP1) -like proteinds; Mycobacterium tuberculosis adapts to cellular stresses by upregulation of the dormancy survival regulon. Hypoxic response protein 1 (HRP1) is encoded by one of the most strongly upregulated genes in the dormancy survival regulon. HRP1 is a 'CBS-domain-only protein; however unlike other CBS containing proteins it does not appear to bind AMP. The biological function of the protein remains unclear, but is thought to contribute to the modulation of the host immune response. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains present in bacteria and eukaryotes; The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair. The interface between the two CBS domains forms a cleft that is a potential ligand binding site. The CBS pair coexists with a variety of other functional domains and this has been used to help in its classification here. It has been proposed that the CBS domain may play a regulatory role, although its exact function is unknown. Mutations of conserved residues within this domain are associated with a variety of human hereditary diseases, including congenital myotonia, idiopathic generalized epilepsy, hypercalciuric nephrolithiasis, and classic Bartter syndrome (CLC chloride channel family members), Wolff-Parkinson-White syndrome (gamma 2 subunit of AMP-activated protein kinase), retinitis pigmentosa (IMP dehydrogenase-1), and homocystinuria (cystathionine beta-synthase).

CBS domain; CBS domains are small intracellular modules that pair together to form a stable globular domain. This family represents a single CBS domain. Pairs of these domains have been termed a Bateman domain. CBS domains have been shown to bind ligands with an adenosyl group such as AMP, ATP and S-AdoMet. CBS domains are found attached to a wide range of other protein domains suggesting that CBS domains may play a regulatory role making proteins sensitive to adenosyl carrying ligands. The region containing the CBS domains in Cystathionine-beta synthase is involved in regulation by S-AdoMet. CBS domain pairs from AMPK bind AMP or ATP. The CBS domains from IMPDH and the chloride channel CLC2 bind ATP.

signal transduction protein with CBS domains; Archeal gamma-subunit of 5'-AMP-activated protein kinase (AMPK) contains four CBS domains in tandem repeats, similar to eukaryotic homologs. AMPK is an important regulator of metabolism and of energy homeostasis. It is a heterotrimeric protein composed of a catalytic serine/threonine kinase subunit (alpha) and two regulatory subunits (beta and gamma). The gamma subunit senses the intracellular energy status by competitively binding AMP and ATP and is believed to be responsible for allosteric regulation of the whole complex. In humans mutations in gamma- subunit of AMPK are associated with hypertrophic cardiomiopathy, Wolff-Parkinson-White syndrome and glycogen storage in the skeletal muscle. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains found in archaea and associated with helix turn helix domain; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains in the inosine 5' monophosphate dehydrogenase (IMPDH) protein. IMPDH is an essential enzyme that catalyzes the first step unique to GTP synthesis, playing a key role in the regulation of cell proliferation and differentiation. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair. The interface between the two CBS domains forms a cleft that is a potential ligand binding site. The CBS pair coexists with a variety of other functional domains and this has been used to help in its classification here. It has been proposed that the CBS domain may play a regulatory role, although its exact function is unknown. Mutations of conserved residues within this domain are associated with a variety of human hereditary diseases, including congenital myotonia, idiopathic generalized epilepsy, hypercalciuric nephrolithiasis, and classic Bartter syndrome (CLC chloride channel family members), Wolff-Parkinson-White syndrome (gamma 2 subunit of AMP-activated protein kinase), retinitis pigmentosa (IMP dehydrogenase-1), and homocystinuria (cystathionine beta-synthase).

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the pyridoxal-phosphate (PALP) dependent enzyme domain; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the pyridoxal-phosphate (PALP) dependent enzyme domain upstream. Cystathionine beta-synthase (CBS ) contains, besides the C-terminal regulatory CBS-pair, an N-terminal heme-binding module, followed by a pyridoxal phosphate (PLP) domain, which houses the active site. It is the first enzyme in the transsulfuration pathway, catalyzing the conversion of serine and homocysteine to cystathionine and water. In general, CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.

The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair. The interface between the two CBS domains forms a cleft that is a potential ligand binding site. The CBS pair coexists with a variety of other functional domains and this has been used to help in its classification here. It has been proposed that the CBS domain may play a regulatory role, although its exact function is unknown. Mutations of conserved residues within this domain are associated with a variety of human hereditary diseases, including congenital myotonia, idiopathic generalized epilepsy, hypercalciuric nephrolithiasis, and classic Bartter syndrome (CLC chloride channel family members), Wolff-Parkinson-White syndrome (gamma 2 subunit of AMP-activated protein kinase), retinitis pigmentosa (IMP dehydrogenase-1), and homocystinuria (cystathionine beta-synthase).

2 tandem repeats of the CBS domain in the two-component sensor histidine kinase and related-proteins, repeat 2; This cd contains 2 tandem repeats of the CBS domain in the two-component sensor histidine kinase and related-proteins. Two-component regulation is the predominant form of signal recognition and response coupling mechanism used by bacteria to sense and respond to diverse environmental stresses and cues ranging from common environmental stimuli to host signals recognized by pathogens and bacterial cell-cell communication signals. The structures of both sensors and regulators are modular, and numerous variations in domain architecture and composition have evolved to tailor to specific needs in signal perception and signal transduction. The simplest histidine kinase sensors consists of only sensing and kinase domains. The more complex hybrid sensors contain an additional REC domain typical of two-component regulators and in some cases a C-terminal histidine phosphotransferase (HPT) domain. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.

signal transduction protein with CBS domains; Archeal gamma-subunit of 5'-AMP-activated protein kinase (AMPK) contains four CBS domains in tandem repeats, similar to eukaryotic homologs. AMPK is an important regulator of metabolism and of energy homeostasis. It is a heterotrimeric protein composed of a catalytic serine/threonine kinase subunit (alpha) and two regulatory subunits (beta and gamma). The gamma subunit senses the intracellular energy status by competitively binding AMP and ATP and is believed to be responsible for allosteric regulation of the whole complex. In humans mutations in gamma- subunit of AMPK are associated with hypertrophic cardiomiopathy, Wolff-Parkinson-White syndrome and glycogen storage in the skeletal muscle. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the pyridoxal-phosphate (PALP) dependent enzyme domain; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the pyridoxal-phosphate (PALP) dependent enzyme domain upstream. Cystathionine beta-synthase (CBS ) contains, besides the C-terminal regulatory CBS-pair, an N-terminal heme-binding module, followed by a pyridoxal phosphate (PLP) domain, which houses the active site. It is the first enzyme in the transsulfuration pathway, catalyzing the conversion of serine and homocysteine to cystathionine and water. In general, CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains found associated with the ABC transporter OpuCA; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains found in association with the ABC transporter OpuCA. OpuCA is the ATP binding component of a bacterial solute transporter that serves a protective role to cells growing in a hyperosmolar environment but the function of the CBS domains in OpuCA remains unknown. In the related ABC transporter, OpuA, the tandem CBS domains have been shown to function as sensors for ionic strength, whereby they control the transport activity through an electronic switching mechanism. ABC transporters are a large family of proteins involved in the transport of a wide variety of different compounds, like sugars, ions, peptides, and more complex organic molecules. They are a subset of nucleotide hydrolases that contain a signature motif, Q-loop, and H-loop/switch region, in addition to the Walker A motif/P-loop and Walker B motif commonly found in a number of ATP- and GTP-binding and hydrolyzing proteins. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the bacterial CAP_ED (cAMP receptor protein effector domain) family of transcription factors, the NT (Nucleotidyltransferase) Pol-beta-like domain, and the DUF294 dom; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the bacterial CAP_ED (cAMP receptor protein effector domain) family of transcription factors, the NT_Pol-beta-like domain, and the DUF294 domain. Members of CAP_ED, include CAP which binds cAMP, FNR (fumarate and nitrate reductase) which uses an iron-sulfur cluster to sense oxygen, and CooA a heme containing CO sensor. In all cases binding of the effector leads to conformational changes and the ability to activate transcription. The NT_Pol-beta-like domain includes the Nucleotidyltransferase (NT) domains of DNA polymerase beta and other family X DNA polymerases, as well as the NT domains of class I and class II CCA-adding enzymes, RelA- and SpoT-like ppGpp synthetases and hydrolases, 2'5'-oligoadenylate (2-5A)synthetases, Escherichia coli adenylyltransferase (GlnE), Escherichia coli uridylyl transferase (GlnD), poly (A) polymerases, terminal uridylyl transferases, Staphylococcus aureus kanamycin nucleotidyltransferase, and similar proteins. DUF294 is a putative nucleotidyltransferase with a conserved DxD motif.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the pyridoxal-phosphate (PALP) dependent enzyme domain; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the pyridoxal-phosphate (PALP) dependent enzyme domain upstream. Cystathionine beta-synthase (CBS ) contains, besides the C-terminal regulatory CBS-pair, an N-terminal heme-binding module, followed by a pyridoxal phosphate (PLP) domain, which houses the active site. It is the first enzyme in the transsulfuration pathway, catalyzing the conversion of serine and homocysteine to cystathionine and water. In general, CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the voltage gated CLC (chloride channel) in archaea; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the voltage gated CLC voltage-gated chloride channel. The CBS pairs here are found in the EriC CIC-type chloride channels in archaea. These ion channels are proteins with a seemingly simple task of allowing the passive flow of chloride ions across biological membranes. CIC-type chloride channels come from all kingdoms of life, have several gene families, and can be gated by voltage. The members of the CIC-type chloride channel are double-barreled: two proteins forming homodimers at a broad interface formed by four helices from each protein. The two pores are not found at this interface, but are completely contained within each subunit, as deduced from the mutational analyses, unlike many other channels, in which four or five identical or structurally related subunits jointly form one pore. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the voltage gated CLC (chloride channel) in bacteria; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the voltage gated CLC voltage-gated chloride channel. The CBS pairs here are found in the EriC CIC-type chloride channels in bacteria. These ion channels are proteins with a seemingly simple task of allowing the passive flow of chloride ions across biological membranes. CIC-type chloride channels come from all kingdoms of life, have several gene families, and can be gated by voltage. The members of the CIC-type chloride channel are double-barreled: two proteins forming homodimers at a broad interface formed by four helices from each protein. The two pores are not found at this interface, but are completely contained within each subunit, as deduced from the mutational analyses, unlike many other channels, in which four or five identical or structurally related subunits jointly form one pore. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair. The interface between the two CBS domains forms a cleft that is a potential ligand binding site. The CBS pair coexists with a variety of other functional domains and this has been used to help in its classification here. It has been proposed that the CBS domain may play a regulatory role, although its exact function is unknown. Mutations of conserved residues within this domain are associated with a variety of human hereditary diseases, including congenital myotonia, idiopathic generalized epilepsy, hypercalciuric nephrolithiasis, and classic Bartter syndrome (CLC chloride channel family members), Wolff-Parkinson-White syndrome (gamma 2 subunit of AMP-activated protein kinase), retinitis pigmentosa (IMP dehydrogenase-1), and homocystinuria (cystathionine beta-synthase).

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with the ACT domain; The putative Acetoin Utilization Protein (Acub) from Vibrio Cholerae contains a CBS pair domain. The acetoin utilization protein plays a role in growth and sporulation on acetoin or butanediol for use as a carbon source. Acetoin is an important physiological metabolite excreted by many microorganisms. It is used as an external energy store by a number of fermentive bacteria. Acetoin is produced by the decarboxylation of alpha-acetolactate. Once superior carbon sources are exhausted, and the culture enters stationary phase, acetoin can be utilised in order to maintain the culture density. The conversion of acetoin into acetyl-CoA or 2,3-butanediol is catalysed by the acetoin dehydrogenase complex and acetoin reductase/2,3-butanediol dehydrogenase, respectively. Acetoin utilization proteins, acetylpolyamine amidohydrolases, and histone deacetylases are members of an ancient protein superfamily.This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains in the acetoin utilization proteins in bacteria. Acetoin is a product of fermentative metabolism in many prokaryotic and eukaryotic microorganisms. They produce acetoin as an external carbon storage compound and then later reuse it as a carbon and energy source during their stationary phase and sporulation. In addition these CBS domains are associated with a downstream ACT (aspartate kinase/chorismate mutase/TyrA) domain, which is linked to a wide range of metabolic enzymes that are regulated by amino acid concentration. Pairs of ACT domains bind specifically to a particular amino acid leading to regulation of the linked enzyme. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.

CBS pair domains found in archeal 5'-AMP-activated protein kinase gamma subunit-like proteins; Archeal gamma-subunit of 5'-AMP-activated protein kinase (AMPK) contains four CBS domains in tandem repeats, similar to eukaryotic homologs. AMPK is an important regulator of metabolism and of energy homeostasis. It is a heterotrimeric protein composed of a catalytic serine/threonine kinase subunit (alpha) and two regulatory subunits (beta and gamma). The gamma subunit senses the intracellular energy status by competitively binding AMP and ATP and is believed to be responsible for allosteric regulation of the whole complex. In humans mutations in gamma- subunit of AMPK are associated with hypertrophic cardiomiopathy, Wolff-Parkinson-White syndrome and glycogen storage in the skeletal muscle. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins.

Two tandem repeats of the cystathionine beta-synthase (CBS pair) domains found in diguanylate cyclase/phosphodiesterase proteins with PAS sensors, repeat 2; This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains found in diguanylate cyclase/phosphodiesterase proteins with PAS sensors. PAS domains have been found to bind ligands, and to act as sensors for light and oxygen in signal transduction. The GGDEF domain has been suggested to be homologous to the adenylyl cyclase catalytic domain and is thought to be involved in regulating cell surface adhesiveness in bacteria. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria. The CBS pair was used as a basis for this cd hierarchy since the human CBS proteins can adopt the typical core structure and form an intramolecular CBS pair. The interface between the two CBS domains forms a cleft that is a potential ligand binding site. The CBS pair coexists with a variety of other functional domains and this has been used to help in its classification here. It has been proposed that the CBS domain may play a regulatory role, although its exact function is unknown. Mutations of conserved residues within this domain are associated with a variety of human hereditary diseases, including congenital myotonia, idiopathic generalized epilepsy, hypercalciuric nephrolithiasis, and classic Bartter syndrome (CLC chloride channel family members), Wolff-Parkinson-White syndrome (gamma 2 subunit of AMP-activated protein kinase), retinitis pigmentosa (IMP dehydrogenase-1), and homocystinuria (cystathionine beta-synthase).

2 tandem repeats of the CBS domain in the two-component sensor histidine kinase and related-proteins, repeat 2; This cd contains 2 tandem repeats of the CBS domain in the two-component sensor histidine kinase and related-proteins. Two-component regulation is the predominant form of signal recognition and response coupling mechanism used by bacteria to sense and respond to diverse environmental stresses and cues ranging from common environmental stimuli to host signals recognized by pathogens and bacterial cell-cell communication signals. The structures of both sensors and regulators are modular, and numerous variations in domain architecture and composition have evolved to tailor to specific needs in signal perception and signal transduction. The simplest histidine kinase sensors consists of only sensing and kinase domains. The more complex hybrid sensors contain an additional REC domain typical of two-component regulators and in some cases a C-terminal histidine phosphotransferase (HPT) domain. The CBS domain, named after human CBS, is a small domain originally identified in cystathionine beta-synthase and is subsequently found in a wide range of different proteins. CBS domains usually occur in tandem repeats. They associate to form a so-called Bateman domain or a CBS pair based on crystallographic studies in bacteria.
