Benzaldehyde dehydrogenase (NAD )

In enzymology, a benzaldehyde dehydrogenase (NAD+) (EC 1.2.1.28) is an enzyme that catalyzes the chemical reaction

The 3 substrates of this enzyme are benzaldehyde, NAD⁺, and H₂O, whereas its 3 products are benzoate, 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 benzaldehyde:NAD+ oxidoreductase. Other names in common use include benzaldehyde (NAD+) dehydrogenase, and benzaldehyde dehydrogenase (NAD+). This enzyme participates in benzoate degradation via hydroxylation and toluene and xylene degradation.
