Aromatase.
based on mapping to UniProt P11511
(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].
-!- The enzyme catalyzes 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-beta- estradiol, respectively.
