Gbu glycine betaine porter and carnitine uptake in osmotically stressed Listeria monocytogenes cells.
The food-borne pathogen Listeria monocytogenes grows actively under high-salt conditions by accumulating compatible solutes such as glycine betaine and carnitine from the medium. We report here that the dominant transport system for glycine betaine uptake, the Gbu porter, may act as a secondary uptake system for carnitine, with a K(m) of 4 mM for carnitine uptake and measurable uptake at carnit...
متن کاملOsmotic control of glycine betaine biosynthesis and degradation in Rhizobium meliloti.
Intracellular accumulation of glycine betaine has been shown to confer an enhanced level of osmotic stress tolerance in Rhizobium meliloti. In this study, we used a physiological approach to investigate the mechanism by which glycine betaine is accumulated in osmotically stressed R. meliloti. Results from growth experiments, 14C labeling of intermediates, and enzyme activity assays are presente...
متن کاملsurvival of normal and chlorine-stressed pathogenic and non-pathogenic vibrio parahaemolyticus under adverse conditions
conclusions chlorine-stressed cells of v. parahaemolyticus were more susceptible to adverse conditions than the non-stressed ones. pathogenic and non-pathogenic strains showed the same survival characteristics under the adverse conditions. these results should be considered in the development of food preservation measures. results findings of the current study revealed that the normal cells of ...
متن کاملThree transport systems for the osmoprotectant glycine betaine operate in Bacillus subtilis: characterization of OpuD.
The accumulation of the osmoprotectant glycine betaine from exogenous sources provides a high degree of osmotic tolerance to Bacillus subtilis. We have identified, through functional complementation of an Escherichia coli mutant defective in glycine betaine uptake, a new glycine betaine transport system from B. subtilis. The DNA sequence of a 2,310-bp segment of the cloned region revealed a sin...
متن کاملthe effect of using critical discourse analytical tools on the improvement of the learners level of critical thinking in reading comprehension
?it is of utmost priority for an experienced teacher to train the mind of the students, and enable them to think critically and correctly. the most important question here is that how to develop such a crucial ability? this study examines a new way to the development of critical thinking utilizing critical discourse analytical tools. to attain this goal, two classes of senior english la...
