【 摘 要 】

DOE funding was used to investigate the role of the phosphotransferase system (PTS) in the symbiotic, nodulating bacterium Sinorhizobium meliloti. This system is well studied in several bacterial species. However, it's organization and function in S. meliloti is substantially different than in the those other, well-studied bacteria. The S. meliloti PTS, through our DOE-funded work, has become a model for how this important signal transduction system works in the a-proteobacteria. We have found that the PTS is relatively simple, used for only signal transduction and not transport, and is involved in regulation of carbon metabolism in response to carbon availability and nitrogen availability.
