Human CYPs are primarily membrane-associated proteins located either in the inner membrane of mitochondria or in the endoplasmic reticulum of cells. CYPs metabolize thousands of endogenous and exogenous chemicals. Some CYPs metabolize only one (or a very few) substrates, such as CYP19 (aromatase), while others may metabolize multiple substrates. Both of these characteristics … WebNational Center for Biotechnology Information
WebAromatase is a cytochrome P450 enzyme that catalyzes a critical step in the conversion of androgens (C19 steroids) to estrogens (C18 steroids). Mutations in the aromatase gene (CYP19A1) can result in a lack of aromatase activity and, as a consequence, impairment in estrogen biosynthesis. The functional consequences of this deficiency begin in ... WebJan 20, 2024 · Applications of the peroxidase activity of cytochrome P450 enzymes in synthetic chemistry remain largely unexplored.
