Abstract excerpt

It has been demonstrated that about 10% of the Escherichia coli genes are under direct or indirect control of RpoS. Therefore, Weber et al. [2005] proposed that this sigma subunit should be considered a second vegetative sigma factor under non-optimal growth conditions. In this report we demonstrate that in the phosphoenolpyruvate:carbohydrate phosphotransferase system-deficient (PTS(-)) derivatives, PB11 and...
