STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

AJR25624.1Nitrogen regulatory protein P-II 1; Indirectly regulates nitrogen metabolism; at high nitrogen levels P-II prevents the phosphorylation of NR-I, the transcriptional activator of the glutamine synthetase gene (glnA); at low nitrogen levels P-II is uridylylated to form PII-UMP and interacts with an adenylyltransferase (GlnE) that activates GlnA; Derived by automated computational analysis using gene prediction method: Protein Homology. (112 aa)    
Predicted Functional Partners:

AJR25691.1
Ammonium transporter; Derived by automated computational analysis using gene prediction method: Protein Homology.

AJR25486.1
Histidine kinase; Derived by automated computational analysis using gene prediction method: Protein Homology.

glnD
protein-PII 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 metabolism.
 
 
 0.984
glnA
Forms a homododecamer; forms glutamine from ammonia and glutamate with the conversion of ATP to ADP and phosphate; also functions in the assimilation of ammonia; highly regulated protein controlled by the addition/removal of adenylyl groups by adenylyltransferase from specific tyrosine residues; addition of adenylyl groups results in inactivation of the enzyme; Derived by automated computational analysis using gene prediction method: Protein Homology.

argB
Acetylglutamate kinase; Catalyzes the ATP-dependent phosphorylation of N-acetyl-L- glutamate; Belongs to the acetylglutamate kinase family. ArgB subfamily.

AJR24134.1
Glutamate synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.

map
Methionine aminopeptidase; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed; Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.
  
    0.539
nadE-2
NAD synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
