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

ntrXNitrogen assimilation regulatory protein NtrX; Function of strongly homologous gene; regulator. (463 aa)    
Predicted Functional Partners:
ntrY
Nitrogen regulation protein NtrY homolog; Function of strongly homologous gene; enzyme.
 
 0.994
ntrB
Nitrogen regulation protein NtrB; Function of strongly homologous gene; enzyme.
 
 0.958
ntrC
Nitrogen assimilation regulatory protein; 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.
 
    
0.857
dusB
tRNA-dihydrouridine synthase B; 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.
  
  
 0.836
trkA
NAD-binding component of TrK potassium transporter; Function of homologous gene experimentally demonstrated in an other organism; transporter.
     
 0.832
XM1_3154
Putative Phosphatases; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
       0.828
XM1_4672
Putative histidine kinase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
 
 
 0.818
hfq
RNA-binding protein Hfq; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family.
   
 0.797
rpoN
RNA polymerase sigma-54 factor(RNA polymerase sigma factor 54,11-496); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
   
 0.769
XM1_3147
Conserved protein of unknown function(containing Cytochrome c assembly protein,62-264); Homologs of previously reported genes of unknown function.
       0.661
