 2,3-dihydroxybenzoate 3,4-dioxygenase

In enzymology, a 2,3-dihydroxybenzoate 3,4-dioxygenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are 2,3-dihydroxybenzoate and O2, whereas its product is 3-carboxy-2-hydroxymuconate semialdehyde.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).
