Vanillin Dehydrogenase

In enzymology, a vanillin dehydrogenase (EC is an enzyme that catalyzes the chemical reaction

+ NAD+ + H2O + NADH + 2 H+

The 3 substrates of this enzyme are vanillin, NAD+, and H2O, whereas its 3 products are vanillate, 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 vanillin:NAD+ oxidoreductase. This enzyme participates in 2,4-dichlorobenzoate degradation.
