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.

prfAPeptide chain release factor RF-1; Peptide chain release factor 1 directs the termination of translation in response to the peptide chain termination codons UAG and UAA. (386 aa)    
Predicted Functional Partners:
hemK
Protein-(glutamine-N5) methyltransferase; Methylates the class 1 translation termination release factors RF1/PrfA and RF2/PrfB on the glutamine residue of the universally conserved GGQ motif; Belongs to the protein N5-glutamine methyltransferase family. PrmC subfamily.
 
 0.996
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.
 
 0.973
rpmE
50S ribosomal protein L31; Binds the 23S rRNA.
  
 
 0.972
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.
 
 0.956
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.
 
 0.946
rpmA
50S ribosomal protein L27; Function of homologous gene experimentally demonstrated in an other organism; structure; Belongs to the bacterial ribosomal protein bL27 family.
 
 0.942
rpsI
30S ribosomal protein S9; Function of homologous gene experimentally demonstrated in an other organism; structure; Belongs to the universal ribosomal protein uS9 family.
 
 0.937
lepA
GTP-binding protein LepA; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.
 
  
 0.936
NIDE0946
Conserved protein of unknown function, putative SAM-dependent methyltransferase; Homologs of previously reported genes of unknown function; 2541254, 3248728, 7607512, 7663118, 7971991; Belongs to the methyltransferase superfamily.
  
 
 0.932
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.
