STRINGSTRING
pth protein (Sinorhizobium fredii NGR234) - STRING interaction network
"pth" - Peptidyl-tRNA hydrolase in Sinorhizobium fredii NGR234
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

pthPeptidyl-tRNA hydrolase; The natural substrate for this enzyme may be peptidyl- tRNAs which drop off the ribosome during protein synthesis; Belongs to the PTH family (239 aa)    
Predicted Functional Partners:
ychF
Ribosome-binding ATPase YchF; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner (367 aa)
   
  0.786
prfA
Peptide chain release factor 1; Peptide chain release factor 1 directs the termination of translation in response to the peptide chain termination codons UAG and UAA (352 aa)
 
   
  0.768
frr
Ribosome-recycling 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 (186 aa)
   
   
  0.767
trpF
annotation not available (224 aa)
 
        0.667
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5’-3’ exonuclease activity (1040 aa)
 
   
  0.660
lepA
Elongation factor 4; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back- translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-dependent manner (611 aa)
 
   
  0.639
prsA
Ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib-5-P); Belongs to the ribose-phosphate pyrophosphokinase family. Class I subfamily (335 aa)
 
      0.627
tsf
Elongation factor Ts; Associates with the EF-Tu.GDP complex and induces the exchange of GDP to GTP. It remains bound to the aminoacyl-tRNA.EF- Tu.GTP complex up to the GTP hydrolysis stage on the ribosome (307 aa)
 
   
  0.613
smpB
SsrA-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 [...] (159 aa)
 
   
  0.612
ybeY
Endoribonuclease YbeY; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3’ terminus of the 16S rRNA (173 aa)
 
          0.597
