Transcriptional switching inEscherichia coliduring stress and starvation by modulation of σ70activity

During active growth of Escherichia coli, majority of the transcriptional activity is carried out by the housekeeping sigma factor (sigma(70)), whose association with core RNAP is generally favoured because of its higher intracellular level and higher affinity to core RNAP. In order to facilitate tr... View More
