In enzymology a 4-hydroxybutyrate dehydrogenase (EC 1.1.1.61) is an enzyme that catalyzes the chemical reaction4-hydroxybutanoate + NAD+ succinate semialdehyde + NADH + H+The two substrates of this enzyme are therefore 4-hydroxybutanoic acid and NAD+ whereas its 3 products are succinate semialdehyde 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.
