Function

[CCME_ECOLI] Heme chaperone required for the biogenesis of c-type cytochromes. Transiently binds heme delivered by CcmC and transfers the heme to apo-cytochromes in a process facilitated by CcmF and CcmH.[HAMAP-Rule:MF_01959]

Publication Abstract from PubMed

The concept of metal chaperones involves transient binding of metallic cofactors by specific proteins for delivery to enzymes in which they function. Metal chaperones thus provide a protective, as well as a transport, function. We report the first structure of a heme chaperone, CcmE, which comprises these two functions. We propose that the covalent attachment of heme to an exposed histidine occurs after heme binding at the surface of a rigid molecule with a flexible C-terminal domain. CcmE belongs to a family of proteins with a specific fold, which all share a function in delivery of specific molecular cargo.
