Function and Biology Details

Reactions catalysed: 
(5Z,13E)-(15S)-9-alpha,11-alpha,15-trihydroxyprosta-5,13-dienoate + NADP(+) = (5Z,13E)-(15S)-9-alpha,15-dihydroxy-11-oxoprosta-5,13-dienoate + NADPH
5-alpha-androstan-3-beta,17-beta-diol + NADP(+) = 17-beta-hydroxy-5-alpha-androstan-3-one + NADPH
Testosterone + NAD(+) = androstenedione + NADH
A 3-alpha-hydroxysteroid + NAD(P)(+) = a 3-oxosteroid + 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
Testosterone + NADP(+) = androst-4-ene-3,17-dione + NADPH
