abstract = {L-glutamate (Glu) is the major excitatory transmitter in
mammalian brain. Inadequate concentration of Glu in the
brain correlates to mood disorder. In industry, Glu is used
as a flavour enhancer in food and in foodstuff processing. A
high concentration of Glu has several effects on human
health such as hypersensitive effects, headache and stomach
pain. The presence of Glu in food can be detected by
different analytical methods based on chromatography, or
capillary electrophoresis or amperometric techniques. We
have isolated and characterized a glutamate-binding protein
(GluB) from the Gram-positive bacteria Corynebacterium
glutamicum. Together with GluC protein, GluD protein and the
cytoplasmic protein GluA, GluB permits the transport of Glu
in/out of cell.In this study, we have investigated the
binding features of GluB as well as the effect of
temperature on its structure both in the absence and in the
presence of Glu. The results have showed that GluB has a
high affinity and selectivity versus Glu (nanomolar range)
and the presence of the ligand induces a higher thermal
stability of the protein structure.},
