Testosterone 17beta-dehydrogenase (NADP+) (EC 1.1.1.64, 17-ketoreductase, NADP-dependent testosterone-17beta-oxidoreductase, testosterone 17beta-dehydrogenase (NADP)) is an enzyme with systematic name 17beta-hydroxysteroid:NADP+ 17-oxidoreductase.[1][2][3] This enzyme catalyses the following chemical reaction

testosterone + NADP+ androstenedione + NADPH + H+

Also oxidizes 3-hydroxyhexobarbital to 3-oxohexobarbital.
