STRINGSTRING
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

glnLNitrogen regulation protein NR(II). (349 aa)    
Predicted Functional Partners:
glnG
Nitrogen regulation protein NR(I); Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.
 0.996
glnB
Nitrogen regulatory protein P-II 1; Belongs to the P(II) protein family.
  
 0.985
glnK
Nitrogen regulatory protein P-II 2; Belongs to the P(II) protein family.
  
 
 0.824
glnA
Glutamine synthetase.
  
  
 0.776
amtB
Ammonia channel precursor.
 
 
 0.698
arcB_2
Aerobic respiration control sensor protein ArcB.
 
 
 
 0.654
amt
Ammonia channel precursor.
  
 
 0.644
rpoN
RNA polymerase sigma-54 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
   
 0.629
glnD
Bifunctional uridylyltransferase/uridylyl-removing enzyme; 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.
  
 
 
 0.626
qseF
Transcriptional regulatory protein QseF.
