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

prfBPeptide chain release factor 2 (RF-2); Peptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA. (377 aa)    
Predicted Functional Partners:
rplJL
Fused 50S ribosomal proteins L10 and L7/L12 (modular protein); Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors. Is thus essential for accurate translation; Belongs to the bacterial ribosomal protein bL12 family.
 
 
 0.980
frr
Ribosome recycling factor; Responsible for the release of ribosomes from messenger RNA at the termination of protein biosynthesis. May increase the efficiency of translation by recycling ribosomes from one round of translation to another; Belongs to the RRF family.
 
 
 0.973
rplU
50S ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
   
   0.959
rpmA
50S ribosomal protein L27; Function of homologous gene experimentally demonstrated in an other organism; structure; Belongs to the bacterial ribosomal protein bL27 family.
  
 
 0.951
rplM
50S ribosomal protein L13; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.
  
   0.951
rpsP
30S ribosomal protein S16; Function of homologous gene experimentally demonstrated in an other organism; structure; Belongs to the bacterial ribosomal protein bS16 family.
  
 
 0.950
lysS
Lysyl-tRNA synthetase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the class-II aminoacyl-tRNA synthetase family.
 
 
 0.934
rpsG
30S ribosomal protein S7; 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.
 
 
 0.933
rpsL
30S ribosomal protein S12; Interacts with and stabilizes bases of the 16S rRNA that are involved in tRNA selection in the A site and with the mRNA backbone. Located at the interface of the 30S and 50S subunits, it traverses the body of the 30S subunit contacting proteins on the other side and probably holding the rRNA structure together. The combined cluster of proteins S8, S12 and S17 appears to hold together the shoulder and platform of the 30S subunit.
  
 
 0.931
rplD
50S ribosomal protein L4; Forms part of the polypeptide exit tunnel.
  
 
 0.928
