Cytochrome c-type biogenesis protein (IPR003567)

Short name: Cyt_c_biogenesis

Overlapping homologous superfamilies


Family relationships


Within mitochondria and bacteria, a family of related proteins is involved in the assembly of periplasmic c-type cytochromes: these include CycK [PMID: 7665469], CcmF [PMID: 7635817,PMID: 9043133], NrfE [PMID: 8057835] and CcbS [PMID: 8389979]. These proteins may play a role in guidance of apocytochromes and haem groups for their covalent linkage by the cytochrome-c-haem lyase. Members of the family are probably integral membrane proteins, with up to 16 predicted transmembrane (TM) helices.
