 Hydroxyquinol 1,2-dioxygenase

In enzymology, a hydroxyquinol 1,2-dioxygenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are benzene-1,2,4-triol (hydroxyquinol) and O2, whereas its product is 3-hydroxy-cis,cis-muconate.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).
