Protein name |
RecName:
|
Full=Cytochrome c biogenesis ATP-binding export protein CcmA;
|
|
EC 7.6.2.5;
|
AltName:
|
Full=Heme exporter protein A;
|
|
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 |
RHEA:19261: ATP + H2O + heme b(in) = ADP + H(+) + heme b(out) + phosphate
EC 7.6.2.5
|
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. |
