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

pnpAPolyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. (775 aa)    
Predicted Functional Partners:
rny
Conserved hypothetical protein; Endoribonuclease that initiates mRNA decay. Belongs to the RNase Y family.
  
 
 0.967
rnr
Exoribonuclease R; 3'-5' exoribonuclease that releases 5'-nucleoside monophosphates and is involved in maturation of structured RNAs.
   
  
 0.906
ybeY
Conserved hypothetical protein; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3' terminus of the 16S rRNA.
     
 0.903
mrnC
Conserved hypothetical protein; Involved in correct processing of both the 5' and 3' ends of 23S rRNA precursor. Processes 30S rRNA precursor transcript even in absence of ribonuclease 3 (Rnc); Rnc processes 30S rRNA into smaller rRNA precursors; Belongs to the MrnC RNase family.
     
 0.898
rncS
Ribonuclease III; Digests double-stranded RNA. Involved in the processing of primary rRNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism.
 
  
 0.835
spr1392
Conserved hypothetical protein; Similar to general stress protein GSP13 from Lactococcus lactis subsp. lactis and Bacillus subtilis.
  
   
 0.823
rnj-2
Conserved hypothetical protein; An RNase that has 5'-3' exonuclease and possibly endonuclease activity. Involved in maturation of rRNA and in some organisms also mRNA maturation and/or decay.
 
  
 0.804
rnj
Conserved hypothetical protein; An RNase that has 5'-3' exonuclease and possibly endonuclease activity. Involved in maturation of rRNA and in some organisms also mRNA maturation and/or decay.
 
  
 0.792
DEAD/H
DEAD RNA helicase.
  
 
 0.792
cshA-2
Conserved hypothetical protein; DEAD-box RNA helicase possibly involved in RNA degradation. Unwinds dsRNA in both 5'- and 3'-directions, has RNA-dependent ATPase activity; Belongs to the DEAD box helicase family. CshA subfamily.
  
 
 0.792
