HSD is classified according to the number of the 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. Disease Deficiency of 17-β HSD caused by mutations are the cause of male hermaphroditism. Deficiency of 3-β HSD caused by mutations are the cause of congenital adrenal hyperplasia. Deficiency of 11-β HSD is associated with alcoholic and non-alcoholic chronic liver disease. Structural highlights The structure of 3-α HSD is that of an α/β barrel with the cofactor NADP binding site at the C-terminal of the barrel. Water molecules shown as red spheres.
