Regulation of rRNA transcription correlates with nucleoside triphosphate sensing.

Journal of bacteriology - 1 Nov 2001

Barker M M, Gourse R L

Abstract excerpt

We have previously shown that the activity of the Escherichia coli rRNA promoter rrnB P1 in vitro depends on the concentration of the initiating nucleotide, ATP, and can respond to changes in ATP pools in vivo. We have proposed that this nucleoside triphosphate (NTP) sensing might contribute to regulation of rRNA transcription. To test this model, we have measured the ATP requirements for transcription from 11...
