+ NAD+ + H2O 
+ NADH + 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.
