SYSTEMATIC NAME
IUBMB Comments
biphenyl,NADH:oxygen oxidoreductase (2,3-hydroxylating)
Requires Fe2+. The enzyme from Burkholderia fungorum 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 centre. Chlorine-substituted biphenyls can also act as substrates. Similar to the three-component enzyme systems EC 1.14.12.3 (benzene 1,2-dioxygenase) and EC 1.14.12.11 (toluene dioxygenase).
