Enzyme Information

1.14.12.18

Biphenyl 2,3-dioxygenase.

based on mapping to UniProt P37333

Biphenyl + NADH + O(2) = (1S,2R)-3-phenylcyclohexa-3,5-diene-1,2-diol + NAD(+).

-!- The enzyme from Burkholderia fungorum strain LB400 (previously Pseudomonas sp.) is part of a multicomponent system composed of an NADH:ferredoxin oxidoreductase (FAD cofactor), a [2Fe-2S] Rieske-type ferredoxin, and a terminal oxygenase that contains a [2Fe-2S] Rieske- type iron-sulfur cluster and a catalytic mononuclear nonheme iron center. -!- Chlorine-substituted biphenyls can also act as substrates. -!- Similar to the three-component enzyme systems EC 1.14.12.3 and EC 1.14.12.11.
