ID 1.13.11.39 DE biphenyl-2,3-diol 1,2-dioxygenase. AN 2,3-dihydroxybiphenyl dioxygenase. CA biphenyl-2,3-diol + O2 = 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoate + CA H(+). CC -!- This enzyme participates in the degradation pathway of biphenyl and CC PCB (poly chlorinated biphenyls), and catalyzes the first ring CC cleavage step by incorporating two oxygen atoms into the catechol CC ring formed by EC 1.3.1.56. CC -!- The enzyme from the bacterium Burkholderia xenovorans LB400 can also CC process catechol, 3-methylcatechol, and 4-methylcatechol, but less CC efficiently. CC -!- The enzyme from the carbazole-degrader Pseudomonas resinovorans CC strain CA10 also accepts 2'-aminobiphenyl-2,3-diol. CC -!- The enzyme from Ralstonia sp. SBUG 290 can also accept 1,2- CC dihydroxydibenzofuran and 1,2-dihydroxynaphthalene. CC -!- The enzyme is strongly inhibited by the substrate. CC -!- Not identical with EC 1.13.11.2.
