 7,8-dihydroxykynurenate 8,8a-dioxygenase

In enzymology, a 7,8-dihydroxykynurenate 8,8a-dioxygenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are 7,8-dihydroxykynurenate and O2, whereas its product is 5-(3-carboxy-3-oxopropenyl)-4,6-dihydroxypyridine-2-carboxylate.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).
