Cytochrome c peroxidase
Cytochrome c peroxidase, CCP, or CcP, is a water-soluble heme-containing enzyme of the peroxidase family that takes reducing equivalents from cytochrome c and reduces hydrogen peroxide to water: CCP + H2O2 + 2 ferrocytochrome c + 2H+ → CCP + 2H2O + 2 ferricytochrome c CCP can be derived from aerobically grown yeast strains and can be isolated in both native and recombinant forms with high yield from Saccharomyces cerevisiae. The enzyme’s primary function is to eliminate toxic radical molecules produced by the cell which are harmful to biological systems.
