CYP21A2 (P450c21) in adrenal cortex conducts 21-hydroxylase activity. CYP19A (P450arom, aromatase) in endoplasmic reticulum of gonads, brain, adipose tissue, and elsewhere catalyzes aromatization of androgens to estrogens. Polyunsaturated fatty acids and eicosanoids [ edit] 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 … See more Human CYPs are primarily membrane-associated proteins located either in the inner membrane of mitochondria or in the endoplasmic reticulum of cells.
