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). The oxygen incorporated need not be derived from O2. The systematic name of this enzyme class is biphenyl-2,3-diol:oxygen 1,2-oxidoreductase (decyclizing). Other names in common use include 2,3-dihydroxybiphenyl dioxygenase, and biphenyl-2,3-diol dioxygenase. This enzyme participates in gamma-hexachlorocyclohexane degradation and biphenyl degradation.
