WebCytochrome P450. The cytochromes P450 (CYP) belong to a multigene superfamily of genes that code for an array of enzymes catalyzing the mixed function oxidation of a wide variety of endogenous compounds and xenobiotics including environmental pollutants, proximate mutagens and carcinogens [39–41]. WebCytochrome c is primarily known as an electron-carrying mitochondrial protein. The transition of cytochrome c between the ferrous and ferric states within the cell, makes it an efficient biological electron-transporter and it plays a vital role in cellular oxidations in both plants and animals.
