Phosphorylation of nitrogen regulator I of Escherichia coli induces strong cooperative binding to DNA essential for activation of transcription.
We studied the effect of phosphorylation of nitrogen regulator I (NRI) on its binding properties. Both phosphorylated and unphosphorylated NRI bind linearly to a single binding site but cooperatively to two adjacent binding sites. Cooperative binding of NRI is severely affected by phosphorylation: h...
