Enzyme Information

1.1.1.50
3-alpha-hydroxysteroid 3-dehydrogenase (Si-specific).
based on mapping to UniProt P23457
A 3-alpha-hydroxysteroid + NAD(P)(+) = a 3-oxosteroid + NAD(P)H.
-!- The enzyme acts on androsterone and other 3-alpha-hydroxysteroids and on 9-, 11- and 15-hydroxyprostaglandin. -!- Si-specific with respect to NAD(+) or NADP(+) (cf. EC 1.1.1.213).
