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

smpBtmRNA-binding protein SmpB; Required for rescue of stalled ribosomes mediated by trans- translation. Binds to transfer-messenger RNA (tmRNA), required for stable association of tmRNA with ribosomes. tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB. tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switc [...] (155 aa)    
Predicted Functional Partners:
rpsO
SSU ribosomal protein S15p (S13e); Forms an intersubunit bridge (bridge B4) with the 23S rRNA of the 50S subunit in the ribosome.
 
 
 
 0.993
rpsR
SSU ribosomal protein S18p, zinc-independent; Binds as a heterodimer with protein S6 to the central domain of the 16S rRNA, where it helps stabilize the platform of the 30S subunit; Belongs to the bacterial ribosomal protein bS18 family.
  
 
 
 0.990
rplS
LSU ribosomal protein L19p; 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.
  
 
 0.990
rplM
LSU ribosomal protein L13p (L13Ae); 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.
   
 
 0.990
rpsB
SSU ribosomal protein S2p (SAe); Belongs to the universal ribosomal protein uS2 family.
  
 
 0.990
rplD
LSU ribosomal protein L4p (L1e); Forms part of the polypeptide exit tunnel.
  
 
 0.990
rplW
LSU ribosomal protein L23p (L23Ae); One of the early assembly proteins it binds 23S rRNA. One of the proteins that surrounds the polypeptide exit tunnel on the outside of the ribosome. Forms the main docking site for trigger factor binding to the ribosome; Belongs to the universal ribosomal protein uL23 family.
  
 
 
 0.990
rpsE
SSU ribosomal protein S5p (S2e); Located at the back of the 30S subunit body where it stabilizes the conformation of the head with respect to the body. Belongs to the universal ribosomal protein uS5 family.
   
 
 0.990
rpmA
LSU ribosomal protein L27p; Belongs to the bacterial ribosomal protein bL27 family.
   
 
 0.989
rplU
LSU ribosomal protein L21p; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
