 Biphenyl-2,3-diol 1,2-dioxygenase

Biphenyl-2,3-diol 1,2-dioxygenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are biphenyl-2,3-diol and oxygen, whereas its two products are 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoate and water.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).
