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 1963, Estabrook, Cooper, and Rosenthal described the role of CYP as a catalyst in steroid hormone synthesis and drug metabolism. In plants, these proteins are important for the … WebThis collection explores detailed experimental protocols necessary for setting up a variety of in vitro cytochrome P450 (CYP) assays that are vital in selecting drug candidates in a drug discovery pipeline. Major factors affecting drug metabolism include CYP expression levels, kinetic parameters for individual CYP enzymes, CYP inhibition and induction, time …
