Sysname
3-oxo-5beta-steroid:NADP+ 4,5-oxidoreductase
Reaction(IUBMB)

Comment
The enzyme from human efficiently catalyses the reduction of progesterone, androstenedione, 17alpha-hydroxyprogesterone and testosterone to 5beta-reduced metabolites; it can also act on aldosterone, corticosterone and cortisol, but to a lesser extent [8]. The bile acid intermediates 7alpha,12alpha-dihydroxy-4-cholesten-3-one and 7alpha-hydroxy-4-cholesten-3-one can also act as substrates [9].
