Gentisate 1,2-dioxygenase (EC 1.13.11.4) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are gentisic acid and oxygen. Oxidative ring cleavage gives 3-maleylpyruvic aicd.
This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O2. The systematic name of this enzyme class is gentisate:oxygen 1,2-oxidoreductase (decyclizing). Other names in common use include gentisate oxygenase, 2,5-dihydroxybenzoate dioxygenase, gentisate dioxygenase, and gentisic acid oxidase. This enzyme participates in tyrosine metabolism. It employs one cofactor, iron.
