In enzymology, a vanillyl-alcohol oxidase (EC 1.1.3.38) is an enzyme that catalyzes the chemical reaction

+ O₂ $\rightleftharpoons$ + H₂O₂

Thus, the two substrates of this enzyme are vanillyl alcohol and O₂, whereas its two products are vanillin and H₂O₂.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is vanillyl alcohol:oxygen oxidoreductase. This enzyme is also called 4-hydroxy-2-methoxybenzyl alcohol oxidase. This enzyme participates in 2,4-dichlorobenzoate degradation. It employs one cofactor, FAD.

Structural studies

As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1DZN, 1E0Y, and 1E8G.
