Role of phosphorylated metabolic intermediates in the regulation of glutamine synthetase synthesis in Escherichia coli.

Journal of bacteriology - 1 Oct 1992

Feng J, Atkinson M R, McCleary W, Stock J B, Wanner B L, Ninfa A J

Abstract excerpt

Transcription of the Ntr regulon is controlled by the two-component system consisting of the response regulator NRI (NtrC) and the kinase/phosphatase NRII (NtrB), which both phosphorylates and dephosphorylates NRI. Even though in vitro transcription from nitrogen-regulated promoters requires phosphorylated NRI, NRII-independent activation of NRI also occurs in vivo. We show here that this activation likely...
