OX NCBI_TaxID=272944; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=ATCC VR-613 / Malish 7; RX PubMed=11557893; DOI=10.1126/science.1061471; RA Ogata H., Audic S., Renesto-Audiffren P., Fournier P.-E., Barbe V., RA Samson D., Roux V., Cossart P., Weissenbach J., Claverie J.-M., RA Raoult D.; RT "Mechanisms of evolution in Rickettsia conorii and R. prowazekii."; RL Science 293:2093-2098(2001). CC -!- FUNCTION: Part of the ABC transporter complex CcmAB involved in CC the biogenesis of c-type cytochromes; once thought to export heme, CC this seems not to be the case, but its exact role is uncertain. CC Responsible for energy coupling to the transport system. CC {ECO:0000255|HAMAP-Rule:MF_01707}. CC -!- CATALYTIC ACTIVITY: CC Reaction=ATP + H2O + heme b(in) = ADP + H(+) + heme b(out) + CC phosphate; Xref=Rhea:RHEA:19261, ChEBI:CHEBI:15377, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, CC ChEBI:CHEBI:60344, ChEBI:CHEBI:456216; EC=7.6.2.5; CC Evidence={ECO:0000255|HAMAP-Rule:MF_01707}; CC -!- SUBUNIT: The complex is composed of two ATP-binding proteins CC (CcmA) and two transmembrane proteins (CcmB). {ECO:0000255|HAMAP- CC 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 CC exporter (TC 3.A.1.107) family. {ECO:0000255|HAMAP-Rule:MF_01707}.
