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.

prfBPeptide chain release factor 2; Peptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA. (332 aa)    
Predicted Functional Partners:
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.
   
  0.943
rplT
50S ribosomal protein L20; Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit.
 
 0.936
rplQ
50S ribosomal protein L17; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  0.929
rplS
50S ribosomal protein L19; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.
 
 0.927
rpsF
30S ribosomal protein S6; Binds together with S18 to 16S ribosomal RNA.
  
 
 0.924
rpsP
30S ribosomal protein S16; Binds to lower part of 30S body where it stabilizes two domains; required for efficient assembly of 30S; in Escherichia coli this protein has nuclease activity; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the bacterial ribosomal protein bS16 family.
  
 
 0.923
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.
 
 
 0.919
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.
  
 
 0.918
rpmA
50S ribosomal protein L27; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the bacterial ribosomal protein bL27 family.
  
 
 0.917
rplP
50S ribosomal protein L16; Binds 23S rRNA and is also seen to make contacts with the A and possibly P site tRNAs; Belongs to the universal ribosomal protein uL16 family.
