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

ptsIPhosphoenolpyruvate-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). (602 aa)    
Predicted Functional Partners:
npr
Phosphohistidinoprotein-hexose phosphotransferase component of N-regulated PTS system (Npr); Function of homologous gene experimentally demonstrated in an other organism; transporter.
 
 0.999
XM1_0545
Putative HPr kinase/phosphorylase, regulates carbohydrate metabolism; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
 
   
 0.941
XM1_0543
Phosphotransferase system, mannose/fructose-specific component IIA; Function of strongly homologous gene; transporter.
 
  
 0.937
ptsN
Nitrogen PTS system EIIA component; Function of strongly homologous gene; transporter.

XM1_0540
Conserved protein of unknown function (RmlC-like cupin domain); Homologs of previously reported genes of unknown function.
     
 0.739
XM1_0538
Protein of unknown function; No homology to any previously reported sequences.
       0.718
XM1_0539
Homologs of previously reported genes of unknown function.
       0.718
XM1_0544
Conserved protein of unknown function (containing ATPase/P-loop-containing domain); Displays ATPase and GTPase activities.
     
 0.690
ahcY
Adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
       0.608
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.
