In enzymology, a 4-hydroxymandelate oxidase (EC 1.1.3.19) is an enzyme that catalyzes the chemical reaction
- (S)-2-hydroxy-2-(4-hydroxyphenyl)acetate + O2 [math]\displaystyle{ \rightleftharpoons }[/math] 4-hydroxybenzaldehyde + CO2 + H2O2
Thus, the two substrates of this enzyme are (S)-2-hydroxy-2-(4-hydroxyphenyl)acetate and O2, whereas its 3 products are 4-hydroxybenzaldehyde, CO2, 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 (S)-2-hydroxy-2-(4-hydroxyphenyl)acetate:oxygen 1-oxidoreductase. This enzyme is also called L-4-hydroxymandelate oxidase (decarboxylating). It has 2 cofactors: FAD, and Manganese.
