21-hydroxysteroid dehydrogenase (NAD+)
- 21-hydroxysteroid dehydrogenase (NAD+)
In enzymology, a 21-hydroxysteroid dehydrogenase (NAD+) (EC number|1.1.1.150) is an enzyme that catalyzes the chemical reaction
:pregnan-21-ol + NAD+ pregnan-21-al + NADH + H+
Thus, the two substrates of this enzyme are pregnan-21-ol and NAD+, whereas its 3 products are pregnan-21-al, 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 21-hydroxysteroid:NAD+ 21-oxidoreductase. This enzyme is also called 21-hydroxysteroid dehydrogenase (NAD+).
