5-beta-reductase
Lua error in Module:Infobox at line 235: malformed pattern (missing ']'). Delta4-3-oxosteroid 5beta-reductase (EC 1.3.1.3, 3-oxo-Delta4-steroid 5beta-reductase, 5beta-reductase, androstenedione 5beta-reductase, cholestenone 5beta-reductase, cortisone 5beta-reductase, cortisone beta-reductase, cortisone Delta4-5beta-reductase, steroid 5beta-reductase, testosterone 5beta-reductase, Delta4-3-ketosteroid 5beta-reductase, Delta4-5beta-reductase, Delta4-hydrogenase, 4,5beta-dihydrocortisone:NADP+ Delta4-oxidoreductase, 3-oxo-5beta-steroid:NADP+ Delta4-oxidoreductase) is an enzyme with systematic name 5beta-cholestan-3-one:NADP+ 4,5-oxidoreductase.[1][2][3][4][5][6][7][8][9] This enzyme catalyses the following chemical reaction
- (1) 5beta-cholestan-3-one + NADP+
cholest-4-en-3-one + NADPH + H+ - (2) 17,21-dihydroxy-5beta-pregnane-3,11,20-trione + NADP+ cortisone + NADPH + H+
The human enzyme efficiently acts on progesterone, androstenedione, 17alpha-hydroxyprogesterone and testosterone to 5beta-reduced metabolites. It can also act on aldosterone, corticosterone and cortisol, to some extent.
