Cytochrome c peroxidase (CcP) is a heme-dependent yeast mitochondrial oxidoreductase enzyme that catalyses the the reduction of hydrogen peroxide to water, using reducing equivalents ferrocytochrome c. The catalytic mechanism couples the one-electron oxidation of ferrocytochrome c to the two-electron reduction of hydrogen peroxide to water.
