nucleotide-binding domain (NBD) of tRNA N6-adenosine threonylcarbamoyltransferase (Kae1) and similar proteins mainly from archaea and bacteria; Kae1 (EC 2.3.1.234), also called N6-L-threonylcarbamoyladenine synthase, t(6)A synthase, t(6)A37 threonylcarbamoyladenosine biosynthesis protein Kae1, or tRNA threonylcarbamoyladenosine biosynthesis protein Kae1, is required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. It is a component of the KEOPS complex that is probably involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37. Kae1 likely plays a direct catalytic role in this reaction but requires other protein(s) of the complex to fulfill this activity. The family also includes bifunctional tRNA threonylcarbamoyladenosine biosynthesis protein (EC 2.3.1.234/EC 2.7.11.1), which contains a Kae1 domain and a Bud32 domain. The Kae1 domain may play a catalytic role and the Bud32 domain probably displays kinase activity that regulates Kae1 function.

For example, YgjD along with YeaZ, YjeE, and YrdC have been deemed necessary and sufficient for the tRNA modification.

Structural analysis indicate that YeaZ lacks resemblance to any known protease active site. Together with the absence of a putative zinc-binding motif.

A member from Riemerella anatipestifer, associated with cohemolysin activity, likewise is exported without benefit of a classical signal peptide and shows glycoprotease activity on the test substrate glycophorin. However, archaeal members of this subfamily show unrelated activities as demonstrated in Pyrococcus abyssi: DNA binding, iron binding, apurinic endonuclease activity, genomic association with a kinase domain, and no glycoprotease activity. This family thus pulls together a set of proteins as a homology group that appears to be near-universal in life, yet heterogeneous in assayed function between bacteria and archaea.

tRNA threonylcarbamoyl adenosine modification protein TsaD; This model represents bacterial members of a protein family that is widely distributed. In a few pathogenic species, the protein is exported in a way that may represent an exceptional secondary function. This model plus companion (archaeal) model TIGR03722 together span the prokaryotic member sequences of TIGR00329, a protein family that appears universal in life, and whose broad function is unknown. A member of TIGR03722 has been characterized as a DNA-binding protein with apurinic endopeptidase activity. In contrast, the rare characterized members of the present family show O-sialoglycoprotein endopeptidase (EC. 3.4.24.57) activity after export. These include glycoprotease (gcp) from Pasteurella haemolytica A1 and a cohemolysin from Riemerella anatipestifer (GB|AAG39646.1). The member from Staphylococcus aureus is essential and is related to cell wall dynamics and the modulation of autolysis, but members are also found in the Mycoplasmas (which lack a cell wall). A reasonable hypothesis is that virulence-related activities after export are secondary to a bacterial domain-wide unknown function. [Protein synthesis, tRNA and rRNA base modification]

NodU is a Rhizobium nodulation protein involved in the synthesis of nodulation factors has 6-O-carbamoyltransferase-like activity. 3'-hydroxymethylcephem-O-carbamoyltransferase CmcH (EC 2.1.3.7) is involved in cephamycin (antibiotic) biosynthesis and has 3-hydroxymethylcephem carbamoyltransferase activity. nebramycin 5' synthase TobZ (EC 6.1.2.2) functions as an ATP carbamoyltransferase and tobramycin carbamoyltransferase. Novobiocin biosynthesis protein NovN (EC 2.1.3.12) acts as a carbamoyltransferase that mediates 3'-carbamoylation of the noviosyl ring to produce novobiocin, the final step in the novobiocin biosynthesis pathway. nodulation protein NolNO (EC 2.1.3.-) is involved in the O-carbamoylation of nod factors.

Catalytic domain of bacterial Serine/Threonine kinases, PknB and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily includes many bacterial eukaryotic-type STKs including Staphylococcus aureus PknB (also called PrkC or Stk1), Bacillus subtilis PrkC, and Mycobacterium tuberculosis Pkn proteins (PknB, PknD, PknE, PknF, PknL, and PknH), among others. S. aureus PknB is the only eukaryotic-type STK present in this species, although many microorganisms encode for several such proteins. It is important for the survival and pathogenesis of S. aureus as it is involved in the regulation of purine and pyrimidine biosynthesis, cell wall metabolism, autolysis, virulence, and antibiotic resistance. M. tuberculosis PknB is essential for growth and it acts on diverse substrates including proteins involved in peptidoglycan synthesis, cell division, transcription, stress responses, and metabolic regulation. B. subtilis PrkC is located at the inner membrane of endospores and functions to trigger spore germination. Bacterial STKs in this subfamily show varied domain architectures. The well-characterized members such as S. aureus and M. tuberculosis PknB, and B. subtilis PrkC, contain an N-terminal cytosolic kinase domain, a transmembrane (TM) segment, and mutliple C-terminal extracellular PASTA domains. The PknB subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Protein Kinases; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine or tyrosine residues on protein substrates. PKs make up a large family of serine/threonine kinases (STKs), protein tyrosine kinases (PTKs), and dual-specificity PKs that phosphorylate both serine/threonine and tyrosine residues of target proteins. Majority of protein phosphorylation occurs on serine residues while only 1% occurs on tyrosine residues. Protein phosphorylation is a mechanism by which a wide variety of cellular proteins, such as enzymes and membrane channels, are reversibly regulated in response to certain stimuli. PKs often function as components of signal transduction pathways in which one kinase activates a second kinase, which in turn, may act on other kinases; this sequential action transmits a signal from the cell surface to target proteins, which results in cellular responses. The PK family is one of the largest known protein families with more than 100 homologous yeast enzymes and more than 500 human proteins. A fraction of PK family members are pseudokinases that lack crucial residues for catalytic activity. The mutiplicity of kinases allows for specific regulation according to substrate, tissue distribution, and cellular localization. PKs regulate many cellular processes including proliferation, division, differentiation, motility, survival, metabolism, cell-cycle progression, cytoskeletal rearrangement, immunity, and neuronal functions. Many kinases are implicated in the development of various human diseases including different types of cancer. The PK family is part of a larger superfamily that includes the catalytic domains of RIO kinases, aminoglycoside phosphotransferase, choline kinase, phosphoinositide 3-kinase (PI3K), and actin-fragmin kinase.

Aminoglycoside 3'-phosphotransferase and Choline Kinase family; This family is composed of APH, ChoK, ethanolamine kinase (ETNK), macrolide 2'-phosphotransferase (MPH2'), an unusual homoserine kinase, and uncharacterized proteins with similarity to the N-terminal domain of acyl-CoA dehydrogenase 10 (ACAD10). The members of this family catalyze the transfer of the gamma-phosphoryl group from ATP (or CTP) to small molecule substrates such as aminoglycosides, macrolides, choline, ethanolamine, and homoserine. Phosphorylation of the antibiotics, aminoglycosides and macrolides, leads to their inactivation and to bacterial antibiotic resistance. Phosphorylation of choline, ethanolamine, and homoserine serves as precursors to the synthesis of important biological compounds, such as the major phospholipids, phosphatidylcholine and phosphatidylethanolamine and the amino acids, threonine, methionine, and isoleucine. The APH/ChoK family is part of a larger superfamily that includes the catalytic domains of other kinases, such as the typical serine/threonine/tyrosine protein kinases (PKs), RIO kinases, actin-fragmin kinase (AFK), and phosphoinositide 3-kinase (PI3K).

Catalytic domain of the Serine/Threonine Kinase, Kinase Interacting with Stathmin (also called U2AF homology motif (UHM) kinase 1); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. KIS (or UHMK1) contains an N-terminal kinase domain and a C-terminal domain with a UHM motif, a protein interaction motif initially found in the pre-mRNA splicing factor U2AF. It phosphorylates the splicing factor SF1, which enhances binding to the splice site to promote spliceosome assembly. KIS was first identified as a kinase that interacts with stathmin, a phosphoprotein that plays a role in axon development and microtubule dynamics. It localizes in RNA granules in neurons and is important in neurite outgrowth. The KIS/UHMK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Choline Kinase and similar proteins; This subfamily is composed of bacterial and eukaryotic choline kinases, as well as eukaryotic ethanolamine kinase. ChoK catalyzes the transfer of the gamma-phosphoryl group from ATP (or CTP) to its substrate, choline, producing phosphorylcholine (PCho), a precursor to the biosynthesis of two major membrane phospholipids, phosphatidylcholine (PC), and sphingomyelin (SM). Although choline is the preferred substrate, ChoK also shows substantial activity towards ethanolamine and its N-methylated derivatives. Bacterial ChoK is also referred to as licA protein. ETNK catalyzes the transfer of the gamma-phosphoryl group from CTP to ethanolamine (Etn), the first step in the CDP-Etn pathway for the formation of the major phospholipid, phosphatidylethanolamine (PtdEtn). Unlike ChoK, ETNK shows specific activity for its substrate and displays negligible activity towards N-methylated derivatives of Etn. ChoK plays an important role in cell signaling pathways and the regulation of cell growth. The ChoK subfamily is part of a larger superfamily that includes the catalytic domains of other kinases, such as the typical serine/threonine/tyrosine protein kinases (PKs), RIO kinases, actin-fragmin kinase (AFK), and phosphoinositide 3-kinase (PI3K).

Catalytic domain of the Serine/Threonine kinases, Liver Kinase B1, Calmodulin Dependent Protein Kinase Kinase, and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Both LKB1 and CaMKKs can phosphorylate and activate AMP-activated protein kinase (AMPK). LKB1, also called STK11, serves as a master upstream kinase that activates AMPK and most AMPK-like kinases. LKB1 and AMPK are part of an energy-sensing pathway that links cell energy to metabolism and cell growth. They play critical roles in the establishment and maintenance of cell polarity, cell proliferation, cytoskeletal organization, as well as T-cell metabolism, including T-cell development, homeostasis, and effector function. CaMKKs are upstream kinases of the CaM kinase cascade that phosphorylate and activate CaMKI and CamKIV. They may also phosphorylate other substrates including PKB and AMPK. Vertebrates contain two CaMKKs, CaMKK1 (or alpha) and CaMKK2 (or beta). CaMKK1 is involved in the regulation of glucose uptake in skeletal muscles. CaMKK2 is involved in regulating energy balance, glucose metabolism, adiposity, hematopoiesis, inflammation, and cancer. The LKB1/CaMKK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the yeast Serine/Threonine Kinases, Rad53 and Cds1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Rad53 and Cds1 are the checkpoint kinase 2 (Chk2) homologs found in budding and fission yeast, respectively. They play a central role in the cell's response to DNA lesions to prevent genome rearrangements and maintain genome integrity. They are phosphorylated in response to DNA damage and incomplete replication, and are essential for checkpoint control. They help promote DNA repair by stalling the cell cycle prior to mitosis in the presence of DNA damage. The Rad53/Cds1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.
