Activator of bc1 complex (ABC1) kinases (also called aarF domain containing kinase 3) and similar proteins; This family is composed of the atypical yeast protein kinase Abc1p, its human homolog ADCK3 (also called CABC1), and similar proteins. Abc1p (also called Coq8p) is required for the biosynthesis of Coenzyme Q (ubiquinone or Q), which is an essential lipid component in respiratory electron and proton transport. It is necessary for the formation of a multi-subunit Q-biosynthetic complex and may also function in the regulation of Q synthesis. Human ADCK3 is able to rescue defects in Q synthesis and the phosphorylation state of Coq proteins in yeast Abc1 (or Coq8) mutants. Mutations in ADCK3 cause progressive cerebellar ataxia and atrophy due to Q10 deficiency. Eukaryotes contain at least two more ABC1/ADCK3-like proteins: in humans, these are the putative atypical protein kinases named ADCK1 and ADCK2. In algae and higher plants, ABC1 kinases have proliferated to more than 15 subfamilies, most of which are located in plastids or mitochondria. Eight of these plant ABC1 kinase subfamilies (ABC1K1-8) are specific for photosynthetic organisms. ABC1 kinases are not related to the ATP-binding cassette (ABC) membrane transporter family.

The exact molecular functions of these proteins is not clear, however yeast ABC1 suppresses a cytochrome b mRNA translation defect and is essential for the electron transfer in the bc 1 complex and E. coli AarF is required for ubiquinone production. It has been suggested that members of the ABC1 family are novel chaperonins. These proteins are unrelated to the ABC transporter proteins.

Ubiquinone biosynthetic protein UbiB; UbiB is the prokaryotic homolog of yeast Abc1p and human ADCK3 (aarF domain containing kinase 3).

Uncharacterized bacterial proteins with similarity to Aminoglycoside 3'-phosphotransferase and Choline kinase; This subfamily is composed of uncharacterized bacterial proteins with similarity to APH and ChoK. Other APH/ChoK-like proteins include 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). These proteins 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-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).

5.73e-04
C-terminal catalytic domain of the atypical protein serine kinase, RIO2 kinase; RIO2 is present in archaea and eukaryotes. It contains an N-terminal winged helix (wHTH) domain and a C-terminal RIO kinase catalytic domain. The wHTH domain is primarily seen in DNA-binding proteins, although some wHTH domains may be involved in RNA recognition. RIO2 is essential for survival and is necessary for rRNA cleavage during 40S ribosomal subunit maturation. RIO kinases are atypical protein serine kinases containing a kinase catalytic signature, but otherwise show very little sequence similarity to typical PKs. Serine kinases catalyze the transfer of the gamma-phosphoryl group from ATP to serine residues in protein substrates. The RIO catalytic domain is truncated compared to the catalytic domains of typical PKs, with deletions of the loops responsible for substrate binding. The RIO2 kinase catalytic domain 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), aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K).

Euykaryotic Choline Kinase and similar proteins; This group is composed of eukaryotic choline kinase, ethanolamine kinase, and similar proteins. 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. 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).
