In enzymology, an aryl-aldehyde dehydrogenase (EC is an enzyme that catalyzes the chemical reaction

an aromatic aldehyde + NAD+ + H2O an aromatic acid + NADH + H+

The 3 substrates of this enzyme are aromatic aldehyde, NAD+, and H2O, whereas its 3 products are aromatic acid, 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. The systematic name of this enzyme class is aryl-aldehyde:NAD+ oxidoreductase. This enzyme participates in tyrosine metabolism and biphenyl degradation.
