The alarmone (p)ppGpp mediates physiological-responsive control at the sigma 54-dependent Po promoter.

Molecular microbiology - 1 Feb 1999

Sze C C, Shingler V

Abstract excerpt

Transcription from the Pseudomonas-derived sigma 54-dependent Po promoter of the dmp operon is mediated by the aromatic-responsive regulator DmpR. However, physiological control is superimposed on this regulatory system causing silencing of the DmpR-mediated transcriptional response in rich media until the transition between exponential and stationary phase is reached. Here, the positive role of the nutritional...
