Enzyme Information
| 1.1.1.189 |
Prostaglandin-E(2) 9-reductase.
based on mapping to UniProt P80508
(5Z,13E)-(15S)-9-alpha,11-alpha,15-trihydroxyprosta-5,13-dienoate + NADP(+) = (5Z,13E)-(15S)-11-alpha,15-dihydroxy-9-oxoprosta-5,13-dienoate + NADPH.
-!- Reduces prostaglandin E(2) to prostaglandin F(2)-alpha. -!- A number of other 9-oxo- and 15-oxo-prostaglandin derivatives can also be reduced to the corresponding hydroxy compounds. -!- May be identical with EC 1.1.1.197.

| 1.1.1.149 |
20-alpha-hydroxysteroid dehydrogenase.
based on mapping to UniProt P80508
17-alpha,20-alpha-dihydroxypregn-4-en-3-one + NAD(P)(+) = 17-alpha- hydroxyprogesterone + NAD(P)H.
-!- Re-specific with respect to NAD(P)(+) (cf. EC 1.1.1.62).
