Salicylaldehyde dehydrogenase

In enzymology, salicylaldehyde dehydrogenase is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are salicylaldehyde, oxidised nicotinamide adenine dinucleotide, and water. Its products are salicylic acid, reduced NADH, and a proton.
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 salicylaldehyde:NAD+ oxidoreductase. This enzyme participates in naphthalene and anthracene degradation.
