. "In bacteria, rapid changes in gene expression can be achieved by affecting the activity of RNA polymerase with small molecule effectors during transcription initiation. An important small molecule effector is the initiating nucleoside triphosphate (iNTP). At some promoters, an increasing iNTP concentration stimulates promoter activity, while a decreasing concentration has the opposite effect. Ribosomal RNA (rRNA) promoters from Grampositive Bacillus subtilis are regulated by the concentration of their iNTP. Yet, the sequences of these promoters do not emulate the sequence characteristics of [iNTP]-regulated rRNA promoters of Gram-negative Escherichia coli. Here, we identified the 30-promoter region, corresponding to the transcription bubble, as key for B. subtilis rRNA promoter regulation via the concentration of the iNTP"@en . .
