abstract：:Sub-MIC antibiotics differentially modulate transcription of subsets of genes by unknown mechanisms. Paradoxically, the RNA polymerase inhibitor rifampicin is able to both upmodulate as well as downmodulate transcription when present at sub-MIC levels. In this study, we analyzed DNA sequences required for transcriptio...
