Mixtures of the three highly purified recombinant dicamba O-demethylase components overexpressed in Escherichia coli converted dicamba to DCSA with an efficiency similar to that of the native enzyme, suggesting that all of the components required for optimal enzymatic activity have been identified.

Dicamba O-demethylase is a multicomponent enzyme that catalyzes the conversion of the herbicide 2-methoxy-3,6-dichlorobenzoic acid (dicamba) to 3,6-dichlorosalicylic acid (DCSA).

Dicamba (2-methoxy-3,6-dichlorobenzoic acid) O-demethylase (DMO) is the terminal Rieske oxygenase of a three-component system that includes a ferredoxin and a reductase.

The activity of dicamba O-demethylase was dependent on oxygen and required NADH and Mg (sup2+).

Toxicol Lett. 1991 Dec;59(1-3):175-85.

Chlorfiurecol, trifluralin, alachlor, propham, MCPP and 2,4-DP caused increases in phase I (cytochrome P-450, ethoxycoumarin O-deethylase, and/or aminopyrine N-demethylase) and phase II (microsomal epoxide hydrolase and cytosolic glutathione S-transferase) activities.
Dicamba, at the dose employed, caused mortality and decreases in some of the enzymes monitored.

This first crystal structure of a Rieske demethylase shows that the Rieske oxygenase structural scaffold can be co-opted to perform varied types of reactions on xenobiotic substrates.
