Enzyme Information
| 1.1.1.- |
With NAD(+) or NADP(+) as acceptor.
based on mapping to UniProt Q92506
|
| 1.1.1.62 |
17-beta-estradiol 17-dehydrogenase.
based on mapping to UniProt Q92506
17-beta-estradiol + NAD(P)(+) = estrone + NAD(P)H.
-!- The enzyme oxidizes or reduces the hydroxy/keto group on C(17) of estrogens and androgens in mammals and regulates the biological potency of these steroids. -!- The mammalian enzyme is bifunctional and also catalyzes EC 1.1.1.270. -!- The enzyme also acts on (S)-20-hydroxypregn-4-en-3-one and related compounds, oxidizing the (S)-20-group, but unlike EC 1.1.1.149, it is Si-specific with respect to NAD(P)(+).
|
| 1.1.1.239 |
3-alpha-(17-beta)-hydroxysteroid dehydrogenase (NAD(+)).
based on mapping to UniProt Q92506
Testosterone + NAD(+) = androstenedione + NADH.
-!- Also acts on other 17-beta-hydroxysteroids, on the 3-alpha-hydroxy group of pregnanes and bile acids. -!- Different from EC 1.1.1.50 or EC 1.1.1.213. -!- Formerly EC 1.1.1.63.
