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.

ABC1 atypical kinase-like domain; This family includes ABC1 from yeast and AarF from E. coli. These proteins have a nuclear or mitochondrial subcellular location in eukaryotes. 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). It 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 required in the first monooxygenase step in Q biosynthesis. Mutant strains with disrupted ubiB genes lack Q and accumulate octaprenylphenol, a Q biosynthetic intermediate.

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).

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.
