In enzymology a gentisate 12-dioxygenase (EC 1.13.11.4) is an enzyme that catalyzes the chemical reaction25-dihydroxybenzoate + O2 maleylpyruvateThus the two substrates of this enzyme are 25-dihydroxybenzoate and O2 whereas its product is maleylpyruvate.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).
