Protein attributes

Sequence length	207 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

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 By similarity.
Catalytic activity	ATP + H2O + heme(In) = ADP + phosphate + heme(Out). HAMAP MF_01707
Subunit structure	The complex is composed of two ATP-binding proteins (ccmA) and two transmembrane proteins (ccmB) Probable.
Subcellular location	Cell inner membrane; Peripheral membrane protein By similarity.
Sequence similarities	Belongs to the ABC transporter superfamily. CcmA exporter (TC 3.A.1.107) family. [View classification] Contains 1 ABC transporter domain.
