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. (348 aa)    
Predicted Functional Partners:
ntrC
Nitrogen regulation protein NR; 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; Belongs to the P(II) protein family.
  
 0.988
glnA
glnA: glutamine synthetase, type I.
 
  
 0.884
glnZ
PII-like protein Pz; Belongs to the P(II) protein family.
  
 
 0.845
amtB
Ammonia channel.
 
 
 0.814
rcsC
Sensor kinase protein RcsC; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsC functions as a membrane- associated protein kinase that phosphorylates RcsD in response to environmental signals. The phosphoryl group is then transferred to the response regulator RcsB.
 
 
 
 0.712
arcB
Aerobic respiration control sensor protein ArcB.
 
 
 
 0.696
dctD
Bacterial regulatory, Fis family protein.
 
 0.675
qseF_2
AAA domain family protein.
 
 0.646
glnD
protein-P-II 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.
