7-beta-hydroxysteroid dehydrogenase (NADP+) activity
Definition
Target type: molecularfunction
Catalysis of the reaction: NADP+ + a 7-beta-hydroxysteroid = NADPH + H+ + a 7-oxosteroid. [EC:1.1.1.201, MetaCyc:1.1.1.201-RXN]
7-beta-hydroxysteroid dehydrogenase (NADP+) activity catalyzes the reversible oxidation of a hydroxyl group at the 7-beta position of a steroid molecule, using NADP+ as a cofactor. This enzyme is involved in the biosynthesis of various steroid hormones, including bile acids, androgens, and estrogens. The reaction proceeds via a hydride transfer from the substrate to the NADP+ molecule, resulting in the reduction of NADP+ to NADPH and the oxidation of the steroid molecule. The enzyme exhibits substrate specificity, primarily acting on steroid substrates with a hydroxyl group at the 7-beta position, although some variation in substrate preference may exist depending on the specific enzyme. 7-beta-hydroxysteroid dehydrogenase plays a crucial role in maintaining hormonal homeostasis and regulating steroid metabolism in the body.'
