EC 188.8.131.52 Enzyme
dissimilatory dimethyl sulfide monooxygenase;
dmoAB (gene names);
dimethyl sulfide C-monooxygenase;
dimethylsulfide monooxygenase (ambiguous);
dimethyl sulfide monooxygenase (ambiguous)
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With NADH or NADPH as one donor, and incorporation of one atom of oxygen into the other donor
dimethyl sulfide,NADH:oxygen oxidoreductase
dimethyl sulfide + O2 + NADH + H+ = methanethiol + formaldehyde + NAD+ + H2O [RN:
dimethyl sulfide [CPD:
The enzyme participates exclusively in sulfur dissimilation. It has lower activity with diethyl sulfide and other short-chain alkyl methyl sulfides. Its activity is stimulated by combined addition of FMN, and, after depletion of cations, of Mg2+ and Fe2+. The enzymes from bacteria of the Hyphomicrobium genus are a two component system that includes an FMN-dependent reductase subunit and a monooxygenase subunit.
