STRINGSTRING
smpB protein (Prevotella amnii) - STRING interaction network
"smpB" - Small protein B in Prevotella amnii
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 B ; 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 tra [...] (159 aa)    
Predicted Functional Partners:
rnr
Ribonuclease R ; 3’-5’ exoribonuclease that releases 5’-nucleoside monophosphates and is involved in maturation of structured RNAs (761 aa)
       
  0.897
HMPREF9018_0209
Uncharacterized protein (170 aa)
              0.866
ribF
Riboflavin biosynthesis protein (313 aa)
 
   
  0.832
trmD
tRNA [GM37] methyltransferase ; Specifically methylates guanosine-37 in various tRNAs (225 aa)
 
   
  0.802
tsaD
tRNA threonylcarbamoyladenosine biosynthesis protein TsaD ; Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Is involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaE and TsaB. TsaD likely plays a direct catalytic role in this reaction (352 aa)
 
   
  0.740
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 (119 aa)
 
   
  0.715
map
Peptidase M ; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed (287 aa)
         
  0.707
ribH
6,7-dimethyl-8-ribityllumazine synthase ; Catalyzes the formation of 6,7-dimethyl-8- ribityllumazine by condensation of 5-amino-6-(D- ribitylamino)uracil with 3,4-dihydroxy-2-butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin (158 aa)
       
  0.693
ribE
Riboflavin synthase, alpha subunit (201 aa)
       
    0.675
infC
Translation initiation factor IF-3 ; IF-3 binds to the 30S ribosomal subunit and shifts the equilibrum between 70S ribosomes and their 50S and 30S subunits in favor of the free subunits, thus enhancing the availability of 30S subunits on which protein synthesis initiation begins (227 aa)
