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:
some 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

ptsNPts iia-like nitrogen-regulatory protein ptsn; Seems to have a role in regulating nitrogen assimilation (154 aa)    
Predicted Functional Partners:
fruA
Phosphotransferase system, fructose-specific iibc component; FRU: PTS system, Fru family, IIB component domain protein
 
 0.998
fruI
Phosphoenolpyruvate-protein phosphotransferase; Belongs to the PEP-utilizing enzyme family
 
  
 0.991
ptsH
Putative phosphoryl carrier protein; General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the PTS EIIA domain
 
  
 0.960
DR97_1644
P-loop atpase family protein; Displays ATPase and GTPase activities
 
  
 0.955
raiA
Putative sigma-54 modulation protein; Ribosome hibernation promoting factor; yfiA: ribosomal subunit interface protein
 
  
 0.944
NagF
Putative phosphoenolpyruvate-protein phosphotransferase; PTS_I_fam: phosphoenolpyruvate-protein phosphotransferase
 
   
 0.934
rpoN
Rna polymerase factor sigma-54; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released
 
  
 0.859
era
Gtp-binding protein era; An essential GTPase that binds both GDP and GTP, with rapid nucleotide exchange. Plays a role in 16S rRNA processing and 30S ribosomal subunit biogenesis and possibly also in cell cycle regulation and energy metabolism
     
 0.846
nagE
N-acetylglucosamine pts system eiicba or eiicb component; PTS-II-BC-nag: PTS system, N-acetylglucosamine-specific IIBC component
 
  
 0.836
pfkB
1-phosphofructokinase; Belongs to the carbohydrate kinase PfkB family
 
  
 0.820
