Protein
Cytochrome c biogenesis ATP-binding export protein CcmA
Organism
Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
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.
