Function and Biology Details

Reactions catalysed:
Indan-1-ol + NAD(P)(+) = indanone + NAD(P)H
17-alpha,20-alpha-dihydroxypregn-4-en-3-one + NAD(P)(+) = 17-alpha-hydroxyprogesterone + NAD(P)H
Androsterone + NAD(P)(+) = 5-alpha-androstane-3,17-dione + NAD(P)H
5-alpha-androstan-3-beta,17-beta-diol + NADP(+) = 17-beta-hydroxy-5-alpha-androstan-3-one + NADPH
A 3-alpha-hydroxysteroid + NAD(P)(+) = a 3-oxosteroid + NAD(P)H
Testosterone + NAD(P)(+) = androst-4-ene-3,17-dione + NAD(P)H
Androstan-3-alpha,17-beta-diol + NAD(+) = 17-beta-hydroxyandrostan-3-one + NADH
17-beta-estradiol + NAD(P)(+) = estrone + NAD(P)H
Trans-1,2-dihydrobenzene-1,2-diol + NADP(+) = catechol + NADPH
