Hydroxysteroid dehydrogenase

From Proteopedia

Template:STRUCTURE 1lwi Hydroxysteroid dehydrogenase (HSD) catalyzes the dehydrogenation of hydroxysteroids. HSD is classdified according to the number of carbon it is acting on. 3-α HSD catalyzes the conversion of androsterone to 5α-androstane-3, 17-dione and 17-α estradiol to estrone. 3-α HSD (also named 17-α HSD) is a bile acid-metabolizing enzyme. 7-α HSD is involved in the dehydrogenation of cholanate compounds and is a bile acid-inducible enzyme. 20-α HSD is involved in the control of progesterone level in pregnancy of mice. 11-β HSD converts 11-keto products like cortisone to cortisol. 17-β HSD is involved in the conversion of androstenedione to testosterone. 3-β/17-β HSD catalyzes the reversible dehydrogenation of steroid compounds at position 3 and 17. NAD and NADP are cofactors of HSD.
