Comments [?]

case <OC:Proteobacteria>
Function Part of the energy-coupling factor (ECF) transporter complex CbiMNOQ involved in cobalt import. Presumably responsible for energy coupling to the transport system.
Pathway Cofactor biosynthesis; adenosylcobalamin biosynthesis.
Subunit Forms an energy-coupling factor (ECF) transporter complex composed of an ATP-binding protein (A component, CbiO), a transmembrane protein (T component, CbiQ) and 2 possible substrate-capture proteins (S components, CbiM and CbiN) of unknown stoichimetry.
else
Function ATP-binding (A) component of a common energy-coupling factor (ECF) ABC-transporter complex. Unlike classic ABC transporters this ECF transporter provides the energy necessary to transport a number of different substrates.
Subunit Forms a stable energy-coupling factor (ECF) transporter complex composed of 2 membrane-embedded substrate-binding proteins (S component), 2 ATP-binding proteins (A component) and 2 transmembrane proteins (T component).
end case
case not defined <Property:Membrane> or <Property:Membrane=1>
Subcellular location Cell membrane; Peripheral membrane protein.
else case <Property:Membrane=2>
Subcellular location Cell inner membrane; Peripheral membrane protein.
end case
case <OC:Proteobacteria>
Similarity Belongs to the ABC transporter superfamily. Cobalt importer (TC 3.A.1.18.1) family.
else
Similarity Belongs to the ABC transporter superfamily. Energy-coupling factor EcfA family.

Comments In Proteobacteria is part of a dedicated cobalt transporter; RHOCB is experimentally a member of this family but does not fit the PROSITE profile. In Firmicutes (and probably other bacteria and archaea) this is an ABC subunit of an energy-coupling transporter that imports more than 1 substrate. See: PubMed=18931129; DOI=10.1128/JB.01208-08; Rodionov D.A., Hebbeln P., Eudes A., ter Beek J., Rodionova I.A., Erkens G.B., Slotboom D.J., Gelfand M.S., Osterman A.L., Hanson A.D., Eitinger T.; "A novel class of modular transporters for vitamins in prokaryotes."; J. Bacteriol. 191:42-51(2009). The subunit composition has been determined to be 2S:2T:A1:A2 PMID:23359690.
