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

Reaction
(1) 5β-cholestan-3-one + NADP+ = cholest-4-en-3-one + NADPH + H+; (2) 17,21-dihydroxy-5β-pregnane-3,11,20-trione + NADP+ = cortisone + NADPH + H+
