aromatase EC#: 1.14.14.14; ChemWhat Code: 1375514 Product Name aromatase Example Structure Synonyms Cyp19a, CYP19A1, Cyp19a1a, Cyp19a1b, Cyp19A3, cytochrome P450 aromatase, P450arom EC Number 1.14.14.14 CAS Registry Number Comments A cytochrome P450. The enzyme catalyses three sequential hydroxylations of the androgens androst-4-ene-3,17-dione and testosterone, resulting in their aromatization and forming the estrogens estrone and 17¦Â-estradiol, respectively. Cofactor History Reactions (1) Testosterone + 3 [reduced NADPH–hemoprotein reductase] + 3 O(2) = 17-beta-estradiol + formate + 4 H(2)O + 3 [oxidized NADPH–hemoprotein reductase]. (2) Androst-4-ene-3,17-dione + 3 [reduced NADPH–hemoprotein reductase] + 3 O(2) = estrone + formate + 4 H(2)O + 3 [oxidized NADPH–hemoprotein reductase]. Buy Reagent No reagent supplier?
