OXIDIZED DMSO REDUCTASE EXPOSED TO HEPES BUFFER
Overview
Much is unknown concerning the role of thiolate ligands of molybdenum in, molybdopterin enzymes. It has been suggested that thiolate dissociation, from molybdenum is part of the catalytic mechanism of bis-molybdopterin, enzymes of the dimethyl sulfoxide reductase (DMSOR) family. For DMSOR from, Rhodobacter capsulatus, thiolate dissociation has therefore been, investigated crystallographically, by UV/visible spectroscopy, and by, enzyme assays. When crystallized from sodium citrate, all four thiolates, of DMSOR are within bonding distance of Mo, but after extended exposure to, Na(+)-Hepes, a pair of thiolates dissociates, a mixture of structures, being indicated after shorter exposures to this buffer. DMSOR is stable in, sodium citrate and other buffers but unstable aerobically although ... [(full description)]
