This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. In order to better understand genes regulated by RpoS, the alternative Sigma factor in the Lyme disease spirochete, we are analyzing the promoter regions of genes that are controlled by RpoS. We are mutating the promoter regions of one such gene ospC, to identify sequence elements that confer RpoS-specificity. The wildtype and mutant sequences are fused to a reporter gfp (green fluorescent protein) gene in the context of the shuttle vector and then introduced into B. burgdorferi. The expression of the gfp marker will be monitored by Western blotting in the transformants. The results from this study will help us identify other RpoS-controlled genes in these organisms.
