toggle switch, consisting of two repressors that control each other’s expression, demonstrated bistability and hysteresis (Gardner et al., 2000). The oscillator, consisting of three genes encoding...

Activation of the glnA, glnK, and nac Promoters as Escherichia coli Undergoes the Transition from Nitrogen Excess Growth to Nitrogen Starvation

Atkinson, Mariette R., Blauwkamp, Timothy A., Bondarenko, Vladamir, Studitsky, Vasily, Ninfa, Alexander J.

The nitrogen-regulated genes and operons of the Ntr regulon of Escherichia coli are activated by the enhancer-binding transcriptional activator NRI∼P (NtrC∼P). Here, we examined the activation of...

Context-Dependent Functions of the PII and GlnK Signal Transduction Proteins in Escherichia coli

Atkinson, Mariette R., Blauwkamp, Timothy A., Ninfa, Alexander J.

Two closely related signal transduction proteins, PII and GlnK, have distinct physiological roles in the regulation of nitrogen assimilation. Here, we examined the physiological roles of PII and GlnK...
