The enzyme, characterized from Pseudomonas spp., is involved in a dimethyl sulfide degradation pathway. It is dependent on NAD(P)H-dependent FMN reductase (EC 22.214.171.124, EC 126.96.36.199, or EC 188.8.131.52), which provides it with reduced FMN. The product, methanesulfinate, is oxidized spontaneously to methanesulfonate in the presence of dioxygen and FMNH2.
