Bile-acid 7alpha-dehydroxylase (EC 1.17.99.5 cholate 7alpha-dehydroxylase 7alpha-dehydroxylase bile acid 7-dehydroxylase) is an enzyme with system name deoxycholate:NAD+ oxidoreductase. This enzyme catalyses the following chemical reaction (1) deoxycholate + NAD+ + H2O cholate + NADH + H+ (2) lithocholate + NAD+ + H2O chenodeoxycholate + NADH + H+Bile-acid 7alpha-dehydroxylase is highly specific for bile acid substrates.
