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.

smpBSsrA-binding protein; 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 switches to [...] (163 aa)    
Predicted Functional Partners:
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.
 
 
 
 0.902
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.
  
 
 0.889
rpsE
30S ribosomal protein S5; With S4 and S12 plays an important role in translational accuracy; Belongs to the universal ribosomal protein uS5 family.
   
 
 0.881
rpmA
Similar to Escherichia coli 50S ribosomal protein L27 RpmA SW:RL27_ECOLI (P02427) (84 aa) fasta scores: E(): 3.1e-16, 64.19% id in 81 aa, and to Mycobacterium leprae 50S ribosomal protein L27 ML1466 SW:RL27_MYCLE (Q9CBZ3) (88 aa) fasta scores: E(): 2.7e-24, 83.95% id in 81 aa; Belongs to the bacterial ribosomal protein bL27 family.
   
 
 0.881
rplB
50S ribosomal protein L2; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family.
   
 
 0.880
rpsK
30S ribosomal protein S11; Located on the platform of the 30S subunit, it bridges several disparate RNA helices of the 16S rRNA. Forms part of the Shine- Dalgarno cleft in the 70S ribosome; Belongs to the universal ribosomal protein uS11 family.
  
 
 0.880
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.
   
 
 0.880
rpsB
30S ribosomal protein S2; Similar to Mycobacterium tuberculosis 30S ribosomal protein S2 RpsB or Rv2890c or MT2958 or MTCY274.21c SW:RS2_MYCTU (Q10796) (287 aa) fasta scores: E(): 1.4e-68, 70.94% id in 265 aa, and to Escherichia coli 30S ribosomal protein S2 RpsB or B0169 or Z0180 or ECS0171 SW:RS2_ECOLI (P02351) (240 aa) fasta scores: E(): 2.8e-40, 50.22% id in 225 aa; Belongs to the universal ribosomal protein uS2 family.
   
 
 0.880
rplC
50S ribosomal protein L3; One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit; Belongs to the universal ribosomal protein uL3 family.
   
 
 0.878
rplA
50S ribosomal protein L1; Binds directly to 23S rRNA. The L1 stalk is quite mobile in the ribosome, and is involved in E site tRNA release.
