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

Rru_A1972Phosphoenolpyruvate--protein phosphotransferase. (835 aa)    
Predicted Functional Partners:
Rru_A1970
PTS fructose IIC component.
 
 0.999
Rru_A1971
PfkB; Belongs to the carbohydrate kinase PfkB family.
  
 0.999
Rru_A3446
HPrNtr.
 
 0.999
Rru_A1973
Transcriptional regulator, LacI family.
 
 
 
 0.997
Rru_A3445
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).
 
0.991
Rru_A0009
PTS IIA-like nitrogen-regulatory protein PtsN.
 
  
 0.960
Rru_A3447
PTS system fructose subfamily IIA component.
 
 
 0.899
tuf1
Translation elongation factor 1A (EF-1A/EF-Tu); This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.
   
  
 0.845
tuf2
Translation elongation factor 1A (EF-1A/EF-Tu); This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.
   
  
 0.845
rpsG
SSU ribosomal protein S7P; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the head domain of the 30S subunit. Is located at the subunit interface close to the decoding center, probably blocks exit of the E-site tRNA; Belongs to the universal ribosomal protein uS7 family.
