Molekulare und funktionelle Analyse eines bakteriellen Exporters für organische Moleküle

Compatible Solutes (CS) have the potential to protect cells, enzymes and bioactive compounds. Glucosylglycerol (GG) is known as an efficient CS. The substance, which is a well-known CS in cyanobacteria, is also produced by the plant-associated bacterium Stenotrophomonas rhizophila. Furthermore, it was shown that GG was excreted in high amounts during the early stationary phase. Using molecular tools a MFS-type exporter was found, which is a potential candidate for the selective export of GG. This GG-export system will be characterized by biochemical and molecular methods.
