Data suggest that although HCCS mediates heme attachment to N-terminal cysteine in heme-attachment site (CXXXH) of cytochrome C variants, up to 50% of cytochrome C produced is modified in an oxygen-dependent manner, resulting in a mixed population of cytochrome c. [HCCS = holocytochrome c synthase] PMID: 28617588

Data suggest that the stronger effect of K72A mutation on the peroxidase activity of human versus yeast cytochrome c results from relief of steric interactions between side chains at positions 72 and 81 (Ile in human vs Ala in yeast), which suppresses the dynamics of omega-loop D necessary for the intrinsic peroxidase activity of cytochrome c.

14. proposed that mutation of residue 41, and interaction with cardiolipin, increase peroxidase activity by altering the 40-57 Omega loop and its hydrogen bond network with the propionate of haem ring A; these changes enhance access of hydrogen peroxide and substrate to the haem PMID: 24329121
