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

pnpPolynucleotide phosphorylase (PNPase); Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. (712 aa)    
Predicted Functional Partners:
truB
tRNA pseudouridine synthase; Responsible for synthesis of pseudouridine from uracil-55 in the psi GC loop of transfer RNAs; Belongs to the pseudouridine synthase TruB family. Type 1 subfamily.
 
  
 0.956
infB
Translation initiation factor IF-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; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. IF-2 subfamily.
  
  
 0.924
nusA
Transcription elongation protein nusA (N utilization substance protein A) (L factor); Participates in both transcription termination and antitermination.
 
  
 0.923
rho
Transcription termination factor Rho; 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.
  
  
 0.890
CCQ73023.1
Putative cold shock protein, DEAD-box ATP-dependent RNA helicase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator; Belongs to the DEAD box helicase family.
  
 
 0.889
CCQ74396.1
Putative ATP-dependent RNA helicase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the DEAD box helicase family.
  
 
 0.889
CCQ74884.1
Putative ATP-dependent RNA helicase RhlE; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the DEAD box helicase family.
 
 
 0.889
CCQ75718.1
Homologs of previously reported genes of unknown function.
  
    0.883
rpoB
RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
  
 0.879
rpoA
DNA-directed RNA polymerase alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
