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

ptsHPhosphocarrier protein HPr. (88 aa)    
Predicted Functional Partners:
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).
 
 0.992
ptsI
PEP-protein phosphotransferase of PTS system (enzyme I); 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).
 
 0.991
fruA-2
Phosphoenolpyruvate-dependent sugar phosphotransferase system, EIIA 2; PTS system fructose-specific EIIABC component (Includes: Fructose-specific phosphotransferase enzyme IIA component; Fructose-specific phosphotransferase enzyme IIB component; Fructose permease IIC component).
  
 
 0.988
CEM62560.1
PTS system, beta-glucoside-specific, IIABC component.
  
 0.986
mtlA
PTS system mannitol-specific EIICBA component (Includes: Mannitol permease IIC component; Mannitol-specific phosphotransferase enzyme IIB component; Mannitol-specific phosphotransferase enzyme IIA component).
   
 0.985
CEM61963.1
Putative Protein-N(pi)-phosphohistidine--sugar phosphotransferase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
 
 0.950
ptsH-3
Phosphocarrier protein HPr.
  
  
  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).
 
 
 
 0.928
ptsH-2
Phosphocarrier protein HPr.
  
  
 
0.918
fruA
PTS system fructose-specific EIIABC component.
 
  
 0.910
