In enzymology, 7alpha-hydroxysteroid dehydrogenase (EC 1.1.1.159) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are the bile acid, cholic acid, and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 7-ketodeoxycholic acid, reduced NADH, and a proton. [1] [2] [3] [4] [5]
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 7alpha-hydroxysteroid:NAD+ 7-oxidoreductase. Other names in common use include 7alpha-hydroxy steroid dehydrogenase, and 7alpha-HSDH.
