3-hydroxyanthranilate oxidase (EC 1.10.3.5) (also called 3-HAO) is an enzyme that catalyzes the chemical reaction:[1]

 
O2
H2O2
 
 
 
6-imino-5-oxocyclohexa-1,3-dienecarboxylic acid

The two substrates of this enzyme are 3-hydroxyanthranilic acid and oxygen. Its products are 6-imino-5-oxocyclohexa-1,3-dienecarboxylic acid and hydrogen peroxide.[2][3]

This enzyme belongs to the family of oxidoreductases, specifically those acting on diphenols and related substances as donor with oxygen as acceptor. The systematic name of this enzyme class is 3-hydroxyanthranilate:oxygen oxidoreductase. This enzyme is also called 3-hydroxyanthranilic acid oxidase.
