Protein Domain : ABC1 atypical kinase-like domain IPR004147

Type  Domain
Description  This entry represents a domain found in Escherichia coli UbiB, known in Providencia stuartii as Aarf, which is required for ubiquinone (CoQ) biosynthesis [ , , ]. Some proteins with this domain are described as aarF domain-containing protein kinases (ADCKs). This domain is also found in yeast ABC1 proteins () required for function of the mitochondrial bc1 complex [ ], in which CoQ functions as an essential cofactor. The function of these proteins is not clear. Along with ABC1, UbiB is part of a large family of proteins that contain motifs found in eukaryotic-type protein kinases [ ], but is not known if they have kinase activity and how this would relate to their requirement for the monoxygenase step in CoQ synthesis. A role in regulation of this step by phosphorylation has been speculated [ ].
