3alpha-hydroxycholanate dehydrogenase explained

3-alpha-hydroxycholanate dehydrogenase
Ec Number:1.1.1.52
Cas Number:9028-57-3
Go Code:0047043

In enzymology, a 3alpha-hydroxycholanate dehydrogenase is an enzyme that catalyzes the chemical reaction

3alpha-hydroxy-5beta-cholanate + NAD+

\rightleftharpoons

3-oxo-5beta-cholanate + NADH + H+

Thus, the two substrates of this enzyme are 3alpha-hydroxy-5beta-cholanate and NAD+, whereas its 3 products are 3-oxo-5beta-cholanate, NADH, and H+.

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 3alpha-hydroxy-5beta-cholanate:NAD+ oxidoreductase. This enzyme is also called alpha-hydroxy-cholanate dehydrogenase.
