DESCRIPTION

Also known as DDMC_STEMA, ddmC. 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). Homotrimer (PubMed:15820213, PubMed:19616009, PubMed:19616011). The dicamba O-demethylase multicomponent enzyme system is composed of an oxygenase component (DdmC) and an electron transfer component formed by a ferredoxin reductase (DdmA) and a ferredoxin (DdmB) (PubMed:15855162, PubMed:15820213, PubMed:16535584). In vitro, dicamba O-demethylase assays in which DdmA2 is substituted for DdmA1 demonstrate that the two enzymes possesse nearly identical activities (PubMed:15855162).
