CC -!- FUNCTION: Part of the ABC transporter complex CcmAB involved in the
CC biogenesis of c-type cytochromes; once thought to export heme, this
CC seems not to be the case, but its exact role is uncertain. Responsible
CC for energy coupling to the transport system. {ECO:0000255|HAMAP-
CC Rule:MF_01707}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + heme b(in) = ADP + H(+) + heme b(out) + phosphate;
CC Xref=Rhea:RHEA:19261, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:60344,
CC ChEBI:CHEBI:456216; EC=7.6.2.5; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01707};
CC -!- SUBUNIT: The complex is composed of two ATP-binding proteins (CcmA) and
CC two transmembrane proteins (CcmB). {ECO:0000255|HAMAP-Rule:MF_01707}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01707}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01707}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. CcmA exporter
CC (TC 3.A.1.107) family. {ECO:0000255|HAMAP-Rule:MF_01707}.
