Enzyme Information
| 1.1.1.62 |
17-beta-estradiol 17-dehydrogenase.
based on mapping to UniProt P14061
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)(+).
