STRINGSTRING
smpB protein (Dermacoccus nishinomiyaensis) - STRING interaction network
"smpB" - SsrA-binding protein in Dermacoccus nishinomiyaensis
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

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 [...] (158 aa)    
Predicted Functional Partners:
rpsC
30S ribosomal protein S3; Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation (275 aa)
 
 
  0.906
rpsB
30S ribosomal protein S2; Derived by automated computational analysis using gene prediction method- Protein Homology; Belongs to the universal ribosomal protein uS2 family (308 aa)
 
 
  0.895
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 (121 aa)
 
 
  0.870
rplP
50S ribosomal protein L16; Binds 23S rRNA and is also seen to make contacts with the A and possibly P site tRNAs (139 aa)
 
 
  0.856
rpoB
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (1161 aa)
   
   
  0.845
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 (278 aa)
 
 
  0.840
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5’-3’ exonuclease activity (889 aa)
 
     
  0.838
rpoA
DNA-directed RNA polymerase subunit alpha; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (339 aa)
 
   
  0.838
rpsS
30S ribosomal protein S19; Protein S19 forms a complex with S13 that binds strongly to the 16S ribosomal RNA (93 aa)
 
 
  0.832
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 (135 aa)
