The crystal structure of the molybdenum enzyme dimethylsulphoxide, reductase (DMSOR) has been determined at 1.9 A resolution with substrate, bound at the active site. DMSOR is an oxotransferase which catalyses the, reduction of dimethylsulphoxide (DMSO) to dimethylsulphide (DMS) in a two, stage reaction which is linked to oxygen atom transfer and electron, transfer. In the first step, DMSO binds to reduced (Mo(IV)) enzyme, the, enzyme is oxidised to Mo(VI) with an extra oxygen ligand and DMS is, released. Regeneration of reduced enzyme is achieved by transfer of two, electrons, successively from a specific cytochrome, and release of the, oxygen as water. The enzyme, purified under aerobic conditions, is in the, oxidised (Mo(VI)) state. Addition of a large excess of DMS to the oxidised, ...

[https://www.uniprot.org/uniprot/DSTOR_RHOCA DSTOR_RHOCA] Catalyzes the reduction of dimethyl sulfoxide (DMSO) and trimethylamine N-oxide (TMAO) to dimethyl sulfide (DMS) and trimethylamine, respectively. The terminal DMSO reductase can also use various sulfoxides and N-oxide compounds as terminal electron acceptor in addition to DMSO and TMAO.<ref>PMID:2001248</ref> <ref>PMID:8856102</ref>
