4-hydroxybenzaldehyde dehydrogenase

In enzymology, 4-hydroxybenzaldehyde dehydrogenase is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are 4-hydroxybenzaldehyde, oxidised nicotinamide adenine dinucleotide, and water. Its products are 4-hydroxybenzoic 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 3-hydroxybenzaldehyde:NAD+ oxidoreductase. This enzyme is also called p-hydroxybenzaldehyde dehydrogenase. This enzyme participates in toluene and xylene degradation in bacteria. It is also found in carrots.
