Function and Biology Details

Reactions catalysed:
3-alpha,7-alpha,12-alpha-trihydroxy-5-beta-cholanate + NAD(+) = 3-alpha,12-alpha-dihydroxy-7-oxo-5-beta-cholanate + NADH
(2S,3S)-3-hydroxy-2-methylbutanoyl-CoA + NAD(+) = 2-methylacetoacetyl-CoA + NADH
Testosterone + NAD(+) = androstenedione + NADH
(S)-3-hydroxyacyl-CoA + NAD(+) = 3-oxoacyl-CoA + NADH
Androstan-3-alpha,17-beta-diol + NAD(+) = 17-beta-hydroxyandrostan-3-one + NADH
17-beta-estradiol + NAD(P)(+) = estrone + NAD(P)H
