2-halobenzoate,NADH:oxygen oxidoreductase (1,2-hydroxylating, dehalogenating, decarboxylating)
a 2-halobenzoate + NADH + H+ + O2 = catechol + a halide anion + NAD+ + CO2 [RN:
A multicomponent enzyme system composed of a dioxygenase component and an electron transfer component. The latter contains FAD. The enzyme, characterized from the bacterium Burkholderia cepacia 2CBS, has a broad substrate specificity. Substrates include 2-fluorobenzoate, 2-chlorobenzoate, 2-bromobenzoate, and 2-iodobenzoate, which are processed in this order of preference.
