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

Predicted Functional Partners:
rne
Ribonuclease E.
  
 
 0.996
rhlB
Putative ATP-dependent RNA helicase; DEAD-box RNA helicase involved in RNA degradation. Has RNA- dependent ATPase activity and unwinds double-stranded RNA. Belongs to the DEAD box helicase family. RhlB subfamily.
  
 
 0.996
hfQ
Host factor-I protein(HF-I); RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family.
    
 
 0.980
rho
Transcription termination factor; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template.
  
  
 0.967
pcnB
poly(A) polymerase; Belongs to the tRNA nucleotidyltransferase/poly(A) polymerase family.
  
 
 0.961
rnr
Ribonuclease R (RNase R); 3'-5' exoribonuclease that releases 5'-nucleoside monophosphates and is involved in maturation of structured RNAs. Belongs to the RNR ribonuclease family. RNase R subfamily.
   
  
 0.928
nusA
L factor; Participates in both transcription termination and antitermination.
 
  
 0.900
rnG
Ribonuclease G.
  
 
 0.893
infB
Protein chain initiation factor 2; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex.
  
  
 0.891
rnb
Exoribonuclease II; Involved in mRNA degradation. Hydrolyzes single-stranded polyribonucleotides processively in the 3' to 5' direction.
      
 0.882
