Transcriptional regulators with the LytTR-type output domains are involved in biosynthesis of extracellular polysaccharides, fimbriation, expression of exoproteins, including toxins, and quorum sensing. Included in this AlgR-like group of LytTR/AlgR family response regulators are Streptococcus agalactiae sensory transduction protein LytR, Pseudomonas aeruginosa positive alginate biosynthesis regulatory protein AlgR, Bacillus subtilis sensory transduction protein LytT, and Escherichia coli transcriptional regulatory protein BtsR, which are members of two-component regulatory systems. LytR and LytT are components of regulatory systems that regulate genes involved in cell wall metabolism. AlgR positively regulates the algD gene, which codes for a GDP-mannose dehydrogenase, a key enzyme in the alginate biosynthesis pathway. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 3-102 9.13e-04

sporulation transcription factor Spo0A; Spo0A, the stage 0 sporulation protein A, is a transcription factor critical for the initiation of sporulation. It contains a response regulator receiver domain (pfam00072). In Bacillus subtilis, it works together with response regulator Spo0F and the phosphotransferase Spo0B, both of which are missing from at least some sporulating species and thus not part of the endospore forming bacteria minimal gene set. Spo0A, however, is universal among endospore-forming species. [Cellular processes, Sporulation and germination]

 6-116 1.89e-20

phosphoacceptor receiver (REC) domain of YesN and related helix-turn-helix containing response regulators; This family is composed of uncharacterized response regulators that contain a REC domain and a AraC family helix-turn-helix (HTH) DNA-binding output domain, including Bacillus subtilis uncharacterized transcriptional regulatory protein YesN and Staphylococcus aureus uncharacterized response regulatory protein SAR0214. YesN is a member of the two-component regulatory system YesM/YesN and SAR0214 is a member of the probable two-component regulatory system SAR0215/SAR0214. Also included in this family is the AlgR-like group of LytTR/AlgR family response, which includes Pseudomonas aeruginosa positive alginate biosynthesis regulatory protein AlgR and Bacillus subtilis sensory transduction protein LytT, among others. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 7-101 6.53e-17

phosphoacceptor receiver (REC) domain of response regulators (RRs) and pseudo response regulators (PRRs); Two-component systems (TCSs) involving a sensor and a response regulator are used by bacteria to adapt to changing environments. Processes regulated by two-component systems in bacteria include sporulation, pathogenicity, virulence, chemotaxis, and membrane transport. Response regulators (RRs) share the common phosphoacceptor REC domain and different effector/output domains such as DNA, RNA, ligand-binding, protein-binding, or enzymatic domains. Response regulators regulate transcription, post-transcription or post-translation, or have functions such as methylesterases, adenylate or diguanylate cyclase, c-di-GMP-specific phosphodiesterases, histidine kinases, serine/threonine protein kinases, and protein phosphatases, depending on their output domains. The function of some output domains are still unknown. TCSs are found in all three domains of life - bacteria, archaea, and eukaryotes, however, the presence and abundance of particular RRs vary between the lineages. Archaea encode very few RRs with DNA-binding output domains; most are stand-alone REC domains. Among eukaryotes, TCSs are found primarily in protozoa, fungi, algae, and green plants. REC domains function as phosphorylation-mediated switches within RRs, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of cyclic di-GMP phosphodiesterase response regulator ...
 7-109 6.86e-14

phosphoacceptor receiver (REC) domain of cyclic di-GMP phosphodiesterase response regulator RpfG and similar proteins; Cyclic di-GMP phosphodiesterase response regulator RpfG, together with sensory/regulatory protein RpfC, constitute a two-component system implicated in sensing and responding to the diffusible signal factor (DSF) that is essential for cell-cell signaling. RpfC is a hybrid sensor/histidine kinase that phosphorylates and activates RpfG, which degrades cyclic di-GMP to GMP, leading to the activation of Clp, a global transcriptional regulator that regulates a large set of genes in the DSF pathway. RpfG contains a CheY-like receiver domain attached to a histidine-aspartic acid-glycine-tyrosine-proline (HD-GYP) cyclic di-GMP phosphodiesterase domain. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 7-110 1.63e-11

phosphoacceptor receiver (REC) domain of hybrid sensor histidine kinases/response regulators similar to Arabidopsis thaliana CKI1 and Escherichia coli RcsC; This family is composed of hybrid sensor histidine kinases/response regulators that are sensor histidine kinases (HKs) fused with a REC domain, similar to the sensor histidine kinase CKI1 from Arabidopsis thaliana, which is involved in multi-step phosphorelay (MSP) signaling that mediates responses to a variety of important stimuli in plants. MSP involves a signal being transferred from HKs via histidine phosphotransfer proteins (AHP1-AHP5) to nuclear response regulators. The CKI1 REC domain specifically interacts with the downstream signaling protein AHP2, AHP3 and AHP5. The plant MSP system has evolved from the prokaryotic two-component system (TCS), which allows organisms to sense and respond to changes in environmental conditions. This family also includes bacterial hybrid sensor HKs such as Escherichia coli RcsC, which is a component of the Rcs signalling pathway that controls a variety of physiological functions like capsule synthesis, cell division, and motility. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of cyclic di-GMP phosphodiesterase PA4781 and similar domains; Pseudomonas aeruginosa cyclic di-GMP phosphodiesterase PA4781 contains an N-terminal REC domain and a C-terminal catalytic HD-GYP domain, characteristics of RpfG family response regulators. PA4781 is involved in cyclic di-3',5'-GMP (c-di-GMP) hydrolysis/degradation in a two-step reaction via the linear intermediate pGpG to produce GMP. Its unphosphorylated REC domain prevents accessibility of c-di-GMP to the active site. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 7-114 1.28e-10

phosphoacceptor receiver (REC) domain of DNA-binding transcriptional regulator NtrC; DNA-binding transcriptional regulator NtrC is also called nitrogen regulation protein NR(I) or nitrogen regulator I (NRI). It contains an N-terminal receiver (REC) domain, followed by a sigma-54 interaction domain, and a C-terminal helix-turn-helix DNA-binding domain. It is part of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. DNA-binding response regulator NtrC is phosphorylated by NtrB; phosphorylation of the N-terminal REC domain activates the central sigma-54 interaction domain and leads to the transcriptional activation from promoters that require sigma(54)-containing RNA polymerase. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of LytTR/AlgR family response regulators similar to AgrA; Members of the LytTR/AlgR family of response regulators contain a REC domain and a unique LytTR DNA-binding output domain that lacks the helix-turn-helix motif and consists mostly of beta-strands. Transcriptional regulators with the LytTR-type output domains are involved in biosynthesis of extracellular polysaccharides, fimbriation, expression of exoproteins, including toxins, and quorum sensing. Included in this AgrA-like group of LytTR/AlgR family response regulators are Staphylococcus aureus accessory gene regulator protein A (AgrA) and Streptococcus pneumoniae response regulator ComE, which are members of two-component regulatory systems. AgrA is a global regulator that controls the synthesis of virulence factors and other exoproteins. ComE is part of the ComD-ComE system that is part of a quorum-sensing signaling pathway that controls the development of competence, a physiological state required for genetic transformation. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of FixJ family response regulators; FixJ family response regulators contain an N-terminal receiver domain (REC) and a C-terminal LuxR family helix-turn-helix (HTH) DNA-binding output domain. The Sinorhizobium meliloti two-component system FixL/FixJ regulates nitrogen fixation in response to oxygen during symbiosis. Under microaerobic conditions, the kinase FixL phosphorylates the response regulator FixJ resulting in the regulation of nitrogen fixation genes such as nifA and fixK. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of nitrogen assimilation regulatory protein NtrX and similar proteins; NtrX is part of the two-component regulatory system NtrY/NtrX that is involved in the activation of nitrogen assimilatory genes such as Gln. It is phosphorylated by the histidine kinase NtrY and interacts with sigma-54. NtrX is a member of the NtrC family, characterized by a domain architecture containing an N-terminal REC domain, followed by a central sigma-54 interaction/ATPase domain, and a C-terminal DNA binding domain. NtrC family response regulators are sigma54-dependent transcriptional activators. Also included in this subfamily is Aquifex aeolicus NtrC4. The ability of the central domain to hydrolyze ATP and thus to interact effectively with a complex of RNA polymerase, sigma54, and promoter, is controlled by the phosphorylation status of the REC domain. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 7-101 8.23e-08

phosphoacceptor receiver (REC) domain of chemotaxis response regulator protein-glutamate methylesterase CheB and similar chemotaxis proteins; Methylesterase CheB is a chemotaxis response regulator with an N-terminal REC domain and a C-terminal methylesterase domain. Chemotaxis is a behavior known in motile bacteria that directs their movement in response to chemical gradients. CheB is a phosphorylation-activated response regulator involved in the reversible modification of bacterial chemotaxis receptors. It catalyzes the demethylation of specific methylglutamate residues introduced into the chemoreceptors (methyl-accepting chemotaxis proteins) by CheR. The CheB REC domain packs against the active site of the C-terminal domain and inhibits methylesterase activity by directly restricting access to the active site. Also included in this family is chemotaxis response regulator CheY, which contains a stand-alone REC domain, and an uncharacterized subfamily composed of proteins containing an N-terminal REC domain and a C-terminal CheY-P phosphatase (CheC) domain. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 7-109 1.72e-07

phosphoacceptor receiver (REC) domain of BsPhoP-like OmpR family response regulators; Bacillus subtilis PhoP (BsPhoP) is part of the PhoPR two-component system that participates in a signal transduction network that controls adaptation of the bacteria to phosphate deficiency by regulating (activating or repressing) genes of the Pho regulon upon phosphorylation by PhoR. When activated, PhoPR directs expression of phosphate scavenging enzymes, lowers synthesis of the phosphate-rich wall teichoic acid (WTA) and initiates synthesis of teichuronic acid, a non-phosphate containing replacement anionic polymer. Members of this subfamily belong to the OmpR family of DNA-binding response regulators, which are characterized by a REC domain and a winged helix-turn-helix (wHTH) DNA-binding output effector domain. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of C4-dicarboxylic acid transport protein D (DctD) and similar proteins; C4-dicarboxylic acid transport protein D (DctD) is part of the two-component regulatory system DctB/DctD, which regulates C4-dicarboxylate transport via regulation of expression of the dctPQM operon and dctA. It is an activator of sigma(54)-RNA polymerase holoenzyme that uses the energy released from ATP hydrolysis to stimulate the isomerization of a closed promoter complex to an open complex capable of initiating transcription. DctD is a member of the NtrC family, characterized by a domain architecture containing an N-terminal REC domain, followed by a central sigma-54 interaction/ATPase domain, and a C-terminal DNA binding domain. The ability of the central domain to hydrolyze ATP and thus to interact effectively with a complex of RNA polymerase, sigma54, and promoter, is controlled by the phosphorylation status of the REC domain. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

second phosphoacceptor receiver (REC) domain of Dictyostelium discoideum hybrid signal transduction histidine kinase D and similar domains; Dictyostelium discoideum hybrid signal transduction histidine kinase D (DhkD) is a large protein that contains two histidine kinase (HK) and two REC domains on the intracellular side of a single pass transmembrane domain, and extracellular PAS and PAC domains that likely are involved in ligand binding. This model represents the second REC domain and similar domains. DhkD activates the cAMP phosphodiesterase RegA to ensure proper prestalk and prespore patterning, tip formation, and the vertical elongation of the mound into a finger, in Dictyostelium discoideum. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of chemotaxis protein CheY; The chemotaxis response regulator CheY contains a stand-alone REC domain. Chemotaxis is a behavior known for motile bacteria that directs their movement in response to chemical gradients. CheY is involved in transmitting sensory signals from chemoreceptors to the flagellar motors. Phosphorylated CheY interacts with the flagella switch components FliM and FliY, which causes counterclockwise rotation of the flagella, resulting in smooth swimming. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 6-101 1.80e-05

phosphoacceptor receiver (REC) domain of hybrid sensor histidine kinase/response regulators similar to Pseudomonas savastanoi blue-light-activated histidine kinase; Typically, two-component regulatory systems (TCSs) consist of a sensor (histidine kinase) that responds to specific input(s) by modifying the output of a cognate response regulator (RR). TCSs allow organisms to sense and respond to changes in environmental conditions. Hybrid sensor histidine kinase (HK)/response regulators contain all the elements of a classical TCS in a single polypeptide chain. Pseudomonas savastanoi blue-light-activated histidine kinase is a photosensitive HK and RR that is involved in increased bacterial virulence upon exposure to light. RRs share the common phosphoacceptor REC domain and different effector/output domains such as DNA, RNA, ligand-binding, protein-binding, or enzymatic domains. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of BfmR-like OmpR family response regulators; Acinetobacter baumannii BfmR is part of the BfmR/S two-component system that functions as the master regulator of biofilm initiation. BfmR confers resistance to complement-mediated bactericidal activity, independent of capsular polysaccharide, and also increases resistance to the clinically important antimicrobials meropenem and colistin, making it a potential antimicrobial target. Its inhibition would have the dual benefit of significantly decreasing in vivo survival and increasing sensitivity to selected antimicrobials. Members of this subfamily belong to the OmpR family of DNA-binding response regulators, which are characterized by a REC domain and a winged helix-turn-helix (wHTH) DNA-binding output effector domain. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of Spo0F and similar domains; Spo0F, a stand-alone response regulator containing only a REC domain with no output/effector domain, controls sporulation in Bacillus subtilis through the exchange of a phosphoryl group. Bacillus subtilis forms spores when conditions for growth become unfavorable. The initiation of sporulation is controlled by a phosphorelay (an expanded version of the two-component system) that consists of four main components: a histidine kinase (KinA), a secondary messenger (Spo0F), a phosphotransferase (Spo0B), and a transcription factor (Spo0A).

sporulation transcription factor Spo0A; Spo0A, the stage 0 sporulation protein A, is a transcription factor critical for the initiation of sporulation. It contains a response regulator receiver domain (pfam00072). In Bacillus subtilis, it works together with response regulator Spo0F and the phosphotransferase Spo0B, both of which are missing from at least some sporulating species and thus not part of the endospore forming bacteria minimal gene set. Spo0A, however, is universal among endospore-forming species. [Cellular processes, Sporulation and germination]

 6-101 1.58e-03

phosphoacceptor receiver (REC) domain of Brucella abortus CpdR and CckA, and similar domains; Two-component systems (TCSs), consisting of a sensor and a response regulator, are used by bacteria to adapt to changing environments. Processes regulated by TCSs in bacteria include sporulation, pathogenicity, virulence, chemotaxis and membrane transport. Response regulators share the common phosphoacceptor REC domain and differ output domains such as DNA, RNA, ligand, and protein-binding, or enzymatic domain. CpdR is a stand-alone REC protein. CckA is a sensor histidine kinase containing N-terminal PAS domains and a C-terminal REC domain. CpdR and CckA are components of a regulatory phosphorelay system (composed of CckA, ChpT, CtrA and CpdR) that controls Brucella abortus cell growth, division, and intracellular survival inside mammalian host cells. CckA autophosphorylates in the presence of ATP and transfers a phosphoryl group to the conserved aspartic acid residue on its C-terminal REC domain, which is relayed to the ChpT phosphotransferase. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 6-101 3.98e-03

phosphoacceptor receiver (REC) domain of BaeR-like OmpR family response regulators; BaeR is part of the BaeSR two-component system that is involved in regulating genes that confer multidrug and metal resistance. In Salmonella, BaeSR induces AcrD and MdtABC drug efflux systems, increasing multidrug and metal resistance. In Escherichia coli, BaeR stimulates multidrug resistance via mdtABC (multidrug transporter ABC, formerly known as yegMNO) genes, which encode a resistance-nodulation-cell division (RND) drug efflux system. Members of this subfamily belong to the OmpR family of DNA-binding response regulators, which are characterized by a REC domain and a winged helix-turn-helix (wHTH) DNA-binding output effector domain. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

 6-110 5.88e-03

phosphoacceptor receiver (REC) domain of uncharacterized hybrid sensor histidine kinase/response regulators; Typically, two-component regulatory systems (TCSs) consist of a sensor (histidine kinase) that responds to specific input(s) by modifying the output of a cognate response regulator (RR). TCSs allow organisms to sense and respond to changes in environmental conditions. Hybrid sensor histidine kinase/response regulators contain all the elements of a classical TCS in a single polypeptide chain. RRs share the common phosphoacceptor REC domain and different effector/output domains such as DNA, RNA, ligand-binding, protein-binding, or enzymatic domains. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

In addition, the PilSR TCS regulates flagellum-dependent swimming motility and pilus-dependent twitching motility. PilR contains an N-terminal REC domain, a central sigma-54 interaction domain, and a C-terminal Fis-type helix-turn-helix DNA-binding domain. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.

phosphoacceptor receiver (REC) domain of Nitrate/Nitrite response regulator L (NarL); Nitrate/nitrite response regulator protein NarL contains an N-terminal REC domain and a C-terminal LuxR family helix-turn-helix (HTH) DNA-binding output domain. Escherichia coli NarL activates the expression of the nitrate reductase (narGHJI) and formate dehydrogenase-N (fdnGHI) operons, and represses the transcription of the fumarate reductase (frdABCD) operon in response to a nitrate/nitrite induction signal. Phosphorylation of the NarL REC domain releases the C-terminal HTH output domain that subsequently binds specific DNA promoter sites to repress or activate gene expression. REC domains function as phosphorylation-mediated switches within response regulators, but some also transfer phosphoryl groups in multistep phosphorelays.
