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

PtsNHypothetical protein. (149 aa)    
Predicted Functional Partners:
RapZ
Hypothetical protein; Displays ATPase and GTPase activities.
  
  
 0.947
hprK
HPr kinase/phosphorylase; Catalyzes the ATP- as well as the pyrophosphate-dependent phosphorylation of a specific serine residue in HPr, a phosphocarrier protein of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS). HprK/P also catalyzes the pyrophosphate-producing, inorganic phosphate-dependent dephosphorylation (phosphorolysis) of seryl-phosphorylated HPr (P-Ser-HPr).
 
  
 0.926
PtsP
Phosphoenolpyruvate-protein phosphotransferase; 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. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr).

TW91_0590
Phosphocarrier protein HPr.
 
  
 0.831
TW91_0589
Pts system, iiab component.
 
  
 0.830
TW91_1512
Putative lipoprotein.
       0.773
RaiA
Ribosomal subunit interface protein.
  
  
 0.630
YlqF
Ribosome biogenesis GTP-binding protein YlqF; Required for a late step of 50S ribosomal subunit assembly. Has GTPase activity; Belongs to the TRAFAC class YlqF/YawG GTPase family. MTG1 subfamily.
       0.555
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.
 
  
 0.435
TW91_1664
Ribulose-phosphate 3-epimerase; Belongs to the ribulose-phosphate 3-epimerase family.
  
  
 0.430
