EC 1.14.13.131

Accepted name: dimethyl-sulfide monooxygenase

Reaction: dimethyl sulfide + O2 + NADH + H+ = methanethiol + formaldehyde + NAD+ + H2O

Other name(s): dimethylsulfide monooxygenase

Systematic name: dimethyl sulfide,NADH:oxygen oxidoreductase

Comments: The enzyme 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 enzyme from Hyphomicrobium is a two component system that includes an FMN-dependent reductase subunit and a monooxygenase subunit.
