BRITE hierarchy
Sysname
3alpha-hydroxysteroid:NAD(P)+ 3-oxidoreductase
Reaction(IUBMB)
a 3alpha-hydroxysteroid + NAD(P)+ = a 3-oxosteroid + NAD(P)H + H+ [RN:
R10422 R10423 ]
Reaction(KEGG)
Substrate
Product
Comment
The enzyme acts on multiple 3alpha-hydroxysteroids, such as androsterone and 5 alpha-dihydrotestosterone. The mammalian enzymes are involved in inactivation of steroid hormones, while the bacterial enzymes are involved in steroid degradation. This entry stands for enzymes whose stereo-specificity with respect to NAD+ or NADP+ is not known. [cf. EC
1.1.1.50 , 3alpha-hydroxysteroid 3-dehydrogenase (Si-specific) and EC
1.1.1.213 , 3alpha-hydroxysteroid 3-dehydrogenase (Re-specific)].
