|---|
   2.7.7.59 | UTP + [protein-PII] |
the enzyme is involved in the cascade control of glutamine synthetase |
| 2.7.7.59 | UTP + [protein-PII] |
the enzyme is regulated by Gln and controls the activity of PII signal transduction protein |
| 2.7.7.59 | UTP + [protein-PII] |
enzyme regulates the adenylyltransferase, which itself regulates the glutamine synthetase by adenylylation and deadenylylation, via protein PII uridylylation and deuridylylation |
| 2.7.7.59 | UTP + [protein-PII] |
enzyme is not essential for nitrogen fixation of the host plant |
| 2.7.7.59 | UTP + [protein-PII] |
the enzyme acts as the primary nitrogen sensor in the nitrogen regulation system |
| 2.7.7.59 | UTP + [protein-PII] |
nitrogen-regulation of gene transcription results from the regulation of the phosphorylation state of the enhancer-binding transcription factor NRI. Phosphorylation of NRI is regulated by a bicyclic cascade system containing four regulatory proteins, one of which is EC 2.7.7.59 |
| 2.7.7.59 | UTP + [protein-PII] |
the enzyme is constitutively expressed at a low level. The functioning of the glutamine synthetase adenylylation cascade is regulated by modulation of the activities of uridylyltransferase and adenylyltransferase, rather than by changes in the expression of their genes |
| 2.7.7.59 | UTP + [protein-PII] |
GlnD plays an important role in nitrogen assimilation and metabolism by reversibly regulating the modification of PII proteins, which in turn regulate a variety of other proteins. It is essential for NifA activation, NtrB/NtrC-regulated gene expression, and posttranslational regulation of nitrogenase activity |
