In enzymology an aminobutyraldehyde dehydrogenase (EC 1.2.1.19) is an enzyme that catalyzes the chemical reaction4-aminobutanal + NAD+ + H2O 4-aminobutanoate + NADH + 2 H+The 3 substrates of this enzyme are 4-aminobutanal NAD+ and H2O whereas its 3 products are 4-aminobutanoate NADH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor.
