Protein
Cytochrome c biogenesis ATP-binding export protein CcmA 1
Organism
Cupriavidus metallidurans (strain ATCC 43123 / DSM 2839 / NBRC 102507 / CH34)
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.
Similarity
Belongs to the ABC transporter superfamily. CcmA exporter (TC 3.A.1.107) family.
