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

ntrBTwo component sensor kinase. (382 aa)    
Predicted Functional Partners:
ntrC
Two component response regulator; 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.
 0.998
glnB
Nitrogen regulatory protein PII; Belongs to the P(II) protein family.
  
 0.975
Atu4047
Two component sensor kinase/response regulator hybrid.
 
 
0.877
amtB
Ammonium transporter.
  
 
 0.866
nifR
Nitrogen regulation protein; Catalyzes the synthesis of 5,6-dihydrouridine (D), a modified base found in the D-loop of most tRNAs, via the reduction of the C5-C6 double bond in target uridines; Belongs to the dus family.
  
  
 0.850
glnK
Nitrogen regulatory protein PII; Belongs to the P(II) protein family.
  
 
 0.803
ntrX
Two component response regulator.
 
 0.771
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.
 
   
 0.719
Atu3603
Two component response regulator.
 
 
 0.705
dctD-2
Two component response regulator for C4-dicarboxylate transport.
 
 0.657
