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

ntrCNitrogen 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. (473 aa)    
Predicted Functional Partners:
glnL
Nitrogen regulation protein NR.
 0.996
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.
 
  
 0.895
glnA
glnA: glutamine synthetase, type I.
  
  
 0.661
arcB
Aerobic respiration control sensor protein ArcB.
  
 
 0.654
glnZ
PII-like protein Pz; Belongs to the P(II) protein family.
   
 
 0.649
cheA
Chemotaxis protein CheA.
  
 
 0.636
ttrS
His Kinase A domain protein.
 
 
 0.624
fliM
Flagellar motor switch protein FliM; FliM is one of three proteins (FliG, FliN, FliM) that forms the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation.
  
  
 0.619
fliG
Flagellar motor switch protein FliG; FliG is one of three proteins (FliG, FliN, FliM) that forms the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation.
  
  
 0.615
flhA
Flagellar biosynthesis protein FlhA; Required for formation of the rod structure of the flagellar apparatus. Together with FliI and FliH, may constitute the export apparatus of flagellin; Belongs to the FHIPEP (flagella/HR/invasion proteins export pore) family.
