Vanillate monooxygenase (EC 1.14.13.82) is an enzyme that catalyzes the chemical reaction

+ NADH + H+
 
 
O2
H2O
 
 
 
+ NAD+ + H2C=O
 

The four substrates of this enzyme are vanillic acid, reduced nicotinamide adenine dinucleotide (NADH), oxygen, and a proton. Its products are protocatechuic acid, oxidised NAD+, water, and formaldehyde.[1][2]

This enzyme is an oxidoreductase, acting on paired donors, with molecular oxygen as oxidant and incorporating one of its atoms. The systematic name of this enzyme class is vanillate:oxygen oxidoreductase (demethylating). Other names in common use include 4-hydroxy-3-methoxybenzoate demethylase, and vanillate demethylase. This enzyme participates in vanillin degradation in Pseudomonas bacteria.[3]
