Enzyme Information
| 1.3.1.20 |
Trans-1,2-dihydrobenzene-1,2-diol dehydrogenase.
based on mapping to UniProt P52895
Trans-1,2-dihydrobenzene-1,2-diol + NADP(+) = catechol + NADPH.
|
| 1.1.1.357 |
3-alpha-hydroxysteroid 3-dehydrogenase.
based on mapping to UniProt P52895
A 3-alpha-hydroxysteroid + NAD(P)(+) = a 3-oxosteroid + NAD(P)H.
-!- The enzyme acts on multiple 3-alpha-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 and EC 1.1.1.213).
