show Brenda entryEC number
1.14.13.131
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
Comment
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.
