The 3 substrates of this enzyme are 16alpha-hydroxysteroid, NAD+, and NADP+, whereas its 4 products are 16-oxosteroid, NADH, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 16alpha-hydroxysteroid:NAD(P)+ 16-oxidoreductase. This enzyme is also called 16alpha-hydroxy steroid dehydrogenase.
