Term Name:	androsterone dehydrogenase (B-specific) activity
Synonyms:	3-alpha-HSD activity, 3-alpha-hydroxysteroid dehydrogenase (B-specific) activity, 3alpha-HSD, 3alpha-hydroxysteroid dehydrogenase (B-specific), 3alpha-hydroxysteroid oxidoreductase activity, 3alpha-hydroxysteroid:NAD(P)+ oxidoreductase (B-specific), hydroxyprostaglandin dehydrogenase activity, sterognost 3alpha
Definition:	Catalysis of the reaction: NAD(P)+ + androsterone = NAD(P)H + H+ + 5-alpha-androstane-3,17-dione. The reaction is B-specific (i.e. the pro-S hydrogen is transferred from the 4-position of reduced nicotinamide cofactor) with respect to NAD(P)+.
