Comments [?]

case <OC:Bacteria> or <OG:Mitochondrion>
Function Part of the ABC transporter complex CcmAB involved in the biogenesis of c-type cytochromes; once thought to export heme, this seems not to be the case, but its exact role is uncertain. Responsible for energy coupling to the transport system.
Catalytic activity ATP + H(2)O + heme(In) = ADP + phosphate + heme(Out).
Subunit The complex is composed of two ATP-binding proteins (CcmA) and two transmembrane proteins (CcmB).
Similarity Belongs to the ABC transporter superfamily. CcmA exporter (TC 3.A.1.107) family.
