Regulation of rRNA Transcription Is Remarkably Robust: FIS Compensates for Altered Nucleoside Triphosphate Sensing by Mutant RNA Polymerases at Escherichia coli rrn P1 Promoters

We recently identified Escherichia coli RNA polymerase (RNAP) mutants (RNAP β′ Δ215–220 and β RH454) that form extremely unstable complexes with rRNA P1 (rrn P1) core promoters. The mutant RNAPs reduce transcription and alter growth rate-dependent regulation of rrn P1 core promoters, because the mut...
