FunFam 25437: Biphenyl-2,3-diol 1,2-dioxygenase

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Catechol 2,3-dioxygenase. [EC: 1.13.11.2]
Catechol + O(2) = 2-hydroxymuconate-6-semialdehyde.
  • The enzyme initiates the meta-cleavage pathway of catechol degradation.
  • Formerly EC 1.13.1.2.

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