In enzymology, an estradiol 17alpha-dehydrogenase () is an enzyme that catalyzes the chemical reaction :estradiol-17alpha + NAD(P)+ estrone + NAD(P)H + H+ The three substrates of this enzyme are estradiol-17alpha, NAD+, and NADP+, whereas its four 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 17alpha-hydroxysteroid:NAD(P)+ 17-oxidoreductase. Other names in common use include 17alpha-estradiol dehydrogenase, 17alpha-hydroxy steroid dehydrogenase, 17alpha-hydroxy steroid oxidoreductase, 17alpha-hydroxysteroid oxidoreductase, and estradiol 17alpha-oxidoreductase. This enzyme participates in androgen and estrogen metabolism. ==References== * 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Estradiol 17alpha-dehydrogenase」の詳細全文を読む スポンサード リンク
