Testosterone 17b-dehydrogenase (NADP+)

Testosterone 17beta-dehydrogenase (NADP+) (, 17-ketoreductase, NADP-dependent testosterone-17beta-oxidoreductase, testosterone 17beta-dehydrogenase (NADP)) is an enzyme with systematic name 17beta-hydroxysteroid:NADP+ 17-oxidoreductase. This enzyme catalyses the following chemical reaction


 * testosterone + NADP+ $$\rightleftharpoons$$ androstenedione + NADPH + H+

Also oxidizes 3-hydroxyhexobarbital to 3-oxohexobarbital.
