| case <OC:Pseudomonadati> | |
| 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:Pseudomonadati> | |
| SIMILARITY | Belongs to the ABC transporter superfamily. Nickel/cobalt uptake transporter (NiCoT) (TC 3.A.1.23) family. |
| else | |
| SIMILARITY | Belongs to the ABC transporter superfamily. Energy-coupling factor EcfA family. |

| Comments | In Pseudomonadati is part of a dedicated cobalt transporter; RHOCB is experimentally a member of this family but does not fit the PROSITE profile. In Bacillota (and probably other bacteria and archaea) this is an ABC subunit of an energy-coupling transporter that imports more than 1 substrate.

Bacteriol. 191:42-51(2009). The subunit composition has been determined to be 2S:2T:A1:A2 PMID:23359690. |
