TUNGSTEN-SUSBSTITUTED DMSO REDUCTASE FROM RHODOBACTER CAPSULATUS
Overview
DMSO reductase (DMSOR) from Rhodobacter capsulatus, well-characterised as, a molybdoenzyme, will bind tungsten. Protein crystallography has shown, that tungsten in W-DMSOR is ligated by the dithiolene group of the two, pyranopterins, the oxygen atom of Ser147 plus another oxygen atom, and is, located in a very similar site to that of molybdenum in Mo-DMSOR. These, conclusions are consistent with W L(III)-edge X-ray absorption, EPR and, UV/visible spectroscopic data. W-DMSOR is significantly more active than, Mo-DMSOR in catalysing the reduction of DMSO but, in contrast to the, latter, shows no significant ability to catalyse the oxidation of DMS.
