The transcription of sigma 54 RNA polymerase-dependent nitrogen-regulated genes is activated by nitrogen regulator I (NRI)-phosphate. The kinase NRII is responsible for the phosphorylation of NRI. It has been shown that NRII also has the ability to dephosphorylate NRI-phosphate but only when PII is present at a concentration greatly in excess of that of NRII. We have now shown that glutamate enables PII to stimulate the dephosphorylation of NRI-phosphate when present in equimolar concentration… CONTINUE READING
