Accepted name: dissimilatory dimethyl sulfide monooxygenase
Reaction: dimethyl sulfide + O2 + NADH + H+ = methanethiol + formaldehyde + NAD+ + H2O
Other name(s): dmoAB (gene names); dimethyl sulfide C-monooxygenase; dimethylsulfide monooxygenase (ambiguous); dimethyl sulfide monooxygenase (ambiguous)
Systematic name: dimethyl sulfide,NADH:oxygen oxidoreductase
Comments: 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.
