Protein Kinases, catalytic domain; The protein kinase superfamily is mainly composed of the catalytic domains of serine/threonine-specific and tyrosine-specific protein kinases. It also includes RIO kinases, which are atypical serine protein kinases, aminoglycoside phosphotransferases, and choline kinases. These proteins catalyze the transfer of the gamma-phosphoryl group from ATP to hydroxyl groups in specific substrates such as serine, threonine, or tyrosine residues of proteins.

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).

Phosphotransferase enzyme family; This family consists of bacterial antibiotic resistance proteins, which confer resistance to various aminoglycosides they include: aminoglycoside 3'-phosphotransferase or kanamycin kinase / neomycin-kanamycin phosphotransferase and streptomycin 3''-kinase or streptomycin 3''-phosphotransferase. The aminoglycoside phosphotransferases inactivate aminoglycoside antibiotics via phosphorylation. This family also includes homoserine kinase. This family is related to fructosamine kinase pfam03881.

Euykaryotic Ethanolamine kinase; 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. The Drosophila ETNK is implicated in development and neuronal function. Mammals contain two ETNK proteins, ETNK1 and ETNK2. ETNK1 selectively increases Etn uptake and phosphorylation, as well as PtdEtn synthesis. ETNK2 is found primarily in the liver and reproductive tissues. It plays a critical role in regulating placental hemostasis to support late embryonic development. It may also have a role in testicular maturation. ETNK 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).

N-terminal domain of Acyl-CoA dehydrogenase (ACAD) 10 and 11, and similar proteins; This subfamily is composed of the N-terminal domains of vertebrate ACAD10 and ACAD11, and similar uncharacterized bacterial and eukaryotic proteins. ACADs are a family of flavoproteins that are involved in the beta-oxidation of fatty acyl-CoA derivatives. ACAD deficiency can cause metabolic disorders including muscle fatigue, hypoglycemia, and hepatic lipidosis. There are at least 11 distinct ACADs, some of which show distinct substrate specificities to either straight-chain or branched-chain fatty acids. ACAD10 is widely expressed in human tissues and highly expressed in liver, kidney, pancreas, and spleen. ACAD10 and ACAD11 are both significantly expressed in human brain tissues. They contain a long N-terminal domain with similarity to phosphotransferases with a Protein Kinase fold, which is absent in other ACADs. They may exhibit multiple functions in acyl-CoA oxidation pathways. ACAD11 utilizes substrates with carbon chain lengths of 20 to 26, with optimal activity towards C22CoA. ACAD10 may be associated with an increased risk in type II diabetes. The ACAD10/11-like 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).
