7-alpha-hydroxysteroid dehydrogenase.
based on mapping to UniProt P0AET8
3-alpha,7-alpha,12-alpha-trihydroxy-5-beta-cholanate + NAD(+) = 3-alpha,12-alpha-dihydroxy-7-oxo-5-beta-cholanate + NADH.
-!- Catalyzes the oxidation of the 7-alpha-hydroxy group of bile acids and alcohols both in their free and conjugated forms. -!- The Bacteroides fragilis and Clostridium enzymes can also utilize NADP(+).
