Abstract excerpt
RpoE2 is an extracytoplasmic sigma factor produced by Sinorhizobium meliloti during stationary growth phase. Its inactivation affected the synthesis of the superoxide dismutase, SodC, and catalase, KatC. The absence of SodC within the cell did not result in an increased sensitivity to extracellular superoxides. In contrast, the absence of KatC affected the resistance of S. meliloti to H(2)O(2) during the...
