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 … See more Animals Animals often have more CYP genes than do humans. Reported numbers range from 35 genes in the sponge Amphimedon queenslandica to … See more InterPro subfamilies: • Cytochrome P450, B-class InterPro: IPR002397 • Cytochrome P450, mitochondrial See more Based on the nature of the electron transfer proteins, CYPs can be classified into several groups: Microsomal P450 systems in which electrons are … See more Human CYPs are primarily membrane-associated proteins located either in the inner membrane of mitochondria or in the endoplasmic reticulum of cells. CYPs metabolize … See more The remarkable reactivity and substrate promiscuity of P450s have long attracted the attention of chemists. Recent progress towards realizing the potential of using P450s towards difficult oxidations have included: (i) eliminating the need for natural co-factors … See more WebThe cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. ...
