Cytocrhome c 7 (CcP7) is a cytochrome c peroxidase found in Saccharomyces cerevisiae <ref>DOI: 10.2210/pdb1ml2/pdb</ref> (commonly known as Baker's Yeast). Cytochrome c 7 is a mitochondrial intermembrane space protein and it is thought to keep the organism from undergoing cell death from high concentrations of hydrogen peroxide by converting this toxic compound into water <ref>B.

'''Cytocrhome c 7''' (Cc7) is a three heme-containing protein derived from the sulfur-reducing bacterium ''Desulfuromonas acetoxidans''. Cc7 is located in the mitochondrial intermembrane space of the bacteria where it plays a role in the electron-transfer mechanism <ref>Assfalg M, Bertini I, Bruschi M, Michel C, Turano P.
