Cytochrome P450 - Wikipedia
Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as for hormone synthesis and breakdown. In … See more Genes encoding CYP enzymes, and the enzymes themselves, are designated with the root symbol CYP for the superfamily, followed by a number indicating the gene family, a capital letter indicating the subfamily, and … See more Structure The active site of cytochrome P450 contains a heme-iron center. The iron is tethered to the protein via a cysteine thiolate See more Animals Animals often have more CYP genes than do humans.
