Function

DDMC_STEMA Component of the dicamba O-demethylase multicomponent enzyme system involved in the degradation of the herbicide dicamba (PubMed:15855162, PubMed:15820213, PubMed:16535584). In vitro, catalyzes the O-demethylation of 2-methoxy-3,6-dichlorobenzoic acid (dicamba) to yield 3,6-dichlorosalicylic acid (DCSA) via an exocyclic monooxygenation (PubMed:15855162, PubMed:15820213, PubMed:16535584, PubMed:19616009).^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Dicamba (3,6-dichloro-2-methoxybenzoic acid) is a widely used herbicide that is efficiently degraded by soil microbes. These microbes use a novel Rieske nonheme oxygenase, dicamba monooxygenase (DMO), to catalyze the oxidative demethylation of dicamba to 3,6-dichlorosalicylic acid (DCSA) and formaldehyde. We have determined the crystal structures of DMO in the free state, bound to its substrate dicamba, and bound to the product DCSA at 2.10-1.75 A resolution. The structures show that the DMO active site uses a combination of extensive hydrogen bonding and steric interactions to correctly orient chlorinated, ortho-substituted benzoic-acid-like substrates for catalysis. Unlike other Rieske aromatic oxygenases, DMO oxygenates the exocyclic methyl group, rather than the aromatic ring, of its substrate. 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.
