9.B.14.3.7
Cytochrome c biogenesis protein, CcsA, of 309 aas and 8 TMSs. May be a bifunctional protein with heme transport (export from the cytoplasm to the periplasm) and attachment to apocytochrome c (cytochrome c synthetase) activities. Two heme binding sites have been identified in a homologue, one in the membrane and one on the external surface (on the periplasmic side of the membrane) (Sutherland et al. 2018).
