| amtB | glnB | STM0463 | STM2561 | Putative Amt family, ammonium transport protein; Similar to E. coli probable ammonium transporter (AAC73554.1); Blastp hit to AAC73554.1 (428 aa), 92% identity in aa 1 - 428. | Regulatory protein (P-II) for nitrogen assimilation by glutamine synthetase (ATase); 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 (By similarity). | 0.999 |
| amtB | glnD | STM0463 | STM0214 | Putative Amt family, ammonium transport protein; Similar to E. coli probable ammonium transporter (AAC73554.1); Blastp hit to AAC73554.1 (428 aa), 92% identity in aa 1 - 428. | Uridylyltransferase; Modifies, by uridylylation and deuridylylation, the PII regulatory proteins (GlnB and homologs), in response to the nitrogen status of the cell that GlnD senses through the glutamine level. Under low glutamine levels, catalyzes the conversion of the PII proteins and UTP to PII-UMP and PPi, while under higher glutamine levels, GlnD hydrolyzes PII-UMP to PII and UMP (deuridylylation). Thus, controls uridylylation state and activity of the PII proteins, and plays an important role in the regulation of nitrogen assimilation and metabolism. | 0.938 |

When cellular nitrogen levels are high, the C-terminal adenylyl transferase (AT) inactivates GlnA by covalent transfer of an adenylyl group from ATP to specific tyrosine residue of GlnA, thus reducing its activity. Conversely, when nitrogen levels are low, the N-terminal adenylyl removase (AR) activates GlnA by removing the adenylyl group by phosphorolysis, increasing its activity.

Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes. | 0.817 |

Under conditions of nitrogen limitation, NtrB autophosphorylates and transfers the phosphoryl group to NtrC. In the presence of nitrogen, acts as a phosphatase that dephosphorylates and inactivates NtrC. | 0.918 |
