WebCytochrome P450 (CYP450) enzymes are a diverse group of catalysts that contains 57 members in humans. CYPs are usually membrane-bound and are localized to the inner mitochondrial or endoplasmic reticular membrane. CYPs have oxygenase activity and commonly catalyze redox reactions, involving the oxidation of the substrate and … Cytochrome P450 enzymes also function to metabolize potentially toxic compounds, including drugs and products of endogenous metabolism such as bilirubin, principally in the liver. The Human Genome Project has identified 57 human genes coding for the various cytochrome P450 enzymes. See more 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 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 transferred from NADPH via cytochrome P450 reductase (variously CPR, POR, or … See more Human CYPs are primarily membrane-associated proteins located either in the inner membrane of mitochondria or in the endoplasmic reticulum of … See more The remarkable reactivity and substrate promiscuity of P450s have long attracted the attention of chemists. Recent progress towards realizing … 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 another numeral for the individual gene. … See more Structure The active site of cytochrome P450 contains a heme-iron center.
