Protein attributes

Sequence length	211 AA.
Sequence status	Complete.
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. HAMAP MF_01707
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) By similarity.
Subcellular location	Cell inner membrane; Peripheral membrane protein By similarity HAMAP MF_01707.
Sequence similarities	Belongs to the ABC transporter superfamily. CcmA exporter (TC 3.A.1.107) family. [View classification] Contains 1 ABC transporter domain.
