In enzymology, an estradiol 17beta-dehydrogenase (EC 1.1.1.62) is an enzyme that catalyzes the chemical reaction
- estradiol-17beta + NAD(P)+ [math]\displaystyle{ \rightleftharpoons }[/math] estrone + NAD(P)H + H+
The 3 substrates of this enzyme are estradiol-17beta, NAD+, and NADP+, whereas its 4 products are estrone, 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 estradiol-17beta:NAD(P)+ 17-oxidoreductase. Other names in common use include 20alpha-hydroxysteroid dehydrogenase, 17beta,20alpha-hydroxysteroid dehydrogenase, 17beta-estradiol dehydrogenase, estradiol dehydrogenase, estrogen 17-oxidoreductase, and 17beta-HSD. This enzyme participates in androgen and estrogen metabolism.
