In enzymology, an aryl-alcohol oxidase (EC 1.1.3.7) is an enzyme that catalyzes the chemical reaction In enzymology, an aryl-alcohol oxidase (EC 1.1.3.7) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are aromatic primary alcohol and O2, whereas its two products are aromatic aldehyde 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 aryl-alcohol:oxygen oxidoreductase. Other names in common use include aryl alcohol oxidase, veratryl alcohol oxidase, and arom. alcohol oxidase. As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1E8F, 1E8H, 1QLT, and 1QLU.
