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; Function of homologous gene experimentally demonstrated in an other organism; regulator. (464 aa)    
Predicted Functional Partners:
ntrY
Nitrogen regulation protein ntrY; Function of strongly homologous gene; enzyme.
 0.996
ntrB
Nitrogen regulation protein; Function of homologous gene experimentally demonstrated in an other organism; regulator.
 
 0.949
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.
 
    
0.867
trkA
Trk system potassium uptake protein trkA; Function of strongly homologous gene; transporter.
      0.856
CCQ73805.1
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.
  
  
 0.846
CCQ73798.1
Phosphoglycolate phosphatase; Function of strongly homologous gene; enzyme.
       0.816
dat
D-alanine aminotransferase; Function of strongly homologous gene; enzyme.
       0.816
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.
 
   
 0.777
CCQ74319.1
Putative MCP methyltransferase/methylesterase, putative chemotaxis CheB/CheR fusion protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
 
 0.755
CCQ72713.1
Putative ABC transporter(periplasmic subunit, urea substrate-binding, UrtA; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative transporter.
