STRINGSTRING
smpB protein (Synechocystis sp. PCC6803) - STRING interaction network
"smpB" - Small protein in Synechocystis sp. PCC6803
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

smpBSmall 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 transl [...] (154 aa)    
Predicted Functional Partners:
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 (122 aa)
 
   
  0.902
pgk
Phosphoglycerate kinase (400 aa)
 
     
  0.800
rpsB
30S ribosomal protein S2 (269 aa)
 
   
  0.779
frr
Ribosome releasing 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 (182 aa)
 
   
  0.779
zam
Protein conferring resistance to acetazolamide; Not known; control resistance to the carbonic anhydrase inhibitor acetazolamide (781 aa)
       
  0.776
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication (635 aa)
 
   
  0.768
trmD
tRNA (m1G37) methyltransferase; Specifically methylates guanosine-37 in various tRNAs (231 aa)
 
   
  0.744
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 (130 aa)
         
  0.738
truB
tRNA pseudouridine synthase B; Responsible for synthesis of pseudouridine from uracil- 55 in the psi GC loop of transfer RNAs (296 aa)
 
     
  0.721
rpl1
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 (238 aa)
   
 
  0.711
