A mutant RNA polymerase that forms unusual open promoter complexes

We describe a mutant Escherichia coli RNA polymerase (RNAP) that forms stable open promoter complexes even at −20°C but with a shortened melted region that extends downstream to only position −7. In the presence of initiating transcription substrates, the mutant RNAP undergoes a temperature-dependen...
