A Three-Component Enzyme System Catalyzes the O Demethylation of the Herbicide Dicamba in Pseudomonas maltophilia DI-6

Year: 1997

Type: article

Abstract: An enzyme activity which converts dicamba (2-methoxy-3,6-dichlorobenzoic acid) to 3,6-dichlorosalicylic acid in vitro has been detected in cell lysates of Pseudomonas maltophilia DI-6. Phenyl-Sepharose column chromatography of a partially purified lysate resulted in the separation of this enzyme into three separate protein components tentatively identified as an oxygenase, a ferredoxin, and a reductase. The activity of dicamba O-demethylase was dependent on oxygen and required NADH and Mg(sup2+).
