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

ptsN2Putative nitrogen regulatory IIA protein. (148 aa)    
Predicted Functional Partners:
ptsN1
Putative nitrogen regulatory IIA protein.
  
  
 
0.907
RPA0354
PTS system phosphocarrier protein HPr, nitrogen regulation.
 
  
 0.837
pfkB
Putative 6-phosphofructokinase; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished; Belongs to the carbohydrate kinase PfkB family.
 
  
 0.837
ptsP
Nitrogen regulatory protein PTSI(NTR); Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished; Belongs to the PEP-utilizing enzyme family.
  
  
 0.806
kdpD
Two component osmosensitive K+channel and sensor histidine kinase, KdpD.
  
 
 0.804
RPA0355
PTS system permease (IIAMan), nitrogen regulatory IIA protein; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished.
 
  
 0.779
hpf
Putative sigma-54 modulation protein; Required for dimerization of active 70S ribosomes into 100S ribosomes in stationary phase; 100S ribosomes are translationally inactive and sometimes present during exponential growth.
 
  
 0.718
kdpE
Two-component osmotic transcriptional regulator kdpE, winged helix family.
  
  
 0.712
kdpC
Potassium-transporting atpase c chain, KdpC; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit acts as a catalytic chaperone that increases the ATP-binding affinity of the ATP-hydrolyzing subunit KdpB by the formation of a transient KdpB/KdpC/ATP ternary complex.
  
    0.633
rpoN
RNA polymerase sigma 54 subunit, RpoN; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
  
 0.628
