ENZYME entry: EC 1.14.14.14

PURL: https://purl.expasy.org/enzyme/EC/1.14.14.14
Accepted Name
aromatase
Alternative Name(s)
CYP19A1
estrogen synthetase
Reaction catalysed
  • testosterone + 3 reduced [NADPH--hemoprotein reductase] + 3 O2 = 17beta-estradiol + formate + 3 oxidized [NADPH--hemoprotein reductase] + 4 H2O + 4 H(+)
  • androst-4-ene-3,17-dione + 3 reduced [NADPH--hemoprotein reductase] + 3 O2 = estrone + formate + 3 oxidized [NADPH--hemoprotein reductase] + 4 H2O + 4 H(+)
Comment(s)
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 17beta-estradiol, respectively.
