-[[https://www.uniprot.org/uniprot/GLNB_ECOLI GLNB_ECOLI]] P-II indirectly controls the transcription of the glutamine synthetase gene (glnA). P-II prevents NR-II-catalyzed conversion of NR-I to NR-I-phosphate, the transcriptional activator of GlnA. When P-II is uridylylated to P-II-UMP, these events are reversed. When the ratio of Gln to 2-ketoglutarate decreases, P-II is uridylylated to P-II-UMP, which causes the deadenylation of glutamine synthetase by GlnE, so activating the enzyme.

-== Publication Abstract from PubMed ==
-The structure of the bacterial signal transduction protein P(II) has been refined to an R factor of 13.2% using 3sigma data between 10 and 1.9 A. The crystals exhibited twinning by merohedry and X-ray intensities were corrected using the method of Fisher &amp; Sweet [Fisher &amp; Sweet (1980). Acta Cryst. A36, 755-760] prior to refinement. Our earlier 2.7 A structure [Cheah, Carr, Suffolk, Vasudevan, Dixon &amp; Ollis (1994). Structure, 2, 981-990] served as a starting model. P(II) is a trimeric molecule, each subunit has a mass of 12.4 kDa and contains 112 amino-acid residues. The refined model includes all 1065 protein atoms per subunit plus 312 water molecules. The high-resolution refinement confirms the correctness of our 2.7 A model, although it leads to a redefinition of the extent of various secondary-structural elements. The monomeric structure of P(II) exhibits an interlocking double betaalphabeta fold. This is a stable fold found in a number of proteins with diverse functions. The association of the protein into a trimer leads to a new structure which we describe in detail. The effects of crystal packing forces are discussed and potential interaction sites with other proteins and effector molecules are identified.
