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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

Score
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. (187 aa)    
Predicted Functional Partners:
ychF
GTP-binding protein YchF; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner.
 
  
 0.900
ctc
Ribosomal 5S rRNA E-loop binding protein Ctc/L25/TL5; This is one of the proteins that binds to the 5S RNA in the ribosome where it forms part of the central protuberance. Belongs to the bacterial ribosomal protein bL25 family. CTC subfamily.
 
    0.898
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.
 
   
 0.787
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.
 
   0.754
mfd
Transcription-repair coupling factor; Couples transcription and DNA repair by recognizing RNA polymerase (RNAP) stalled at DNA lesions. Mediates ATP-dependent release of RNAP and its truncated transcript from the DNA, and recruitment of nucleotide excision repair machinery to the damaged site; In the C-terminal section; belongs to the helicase family. RecG subfamily.
  
  
 0.676
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
  
 0.631
polI
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
   
 0.584
hemK
Protein methyltransferase HemK; Methylates the class 1 translation termination release factors RF1/PrfA and RF2/PrfB on the glutamine residue of the universally conserved GGQ motif; Belongs to the protein N5-glutamine methyltransferase family. PrmC subfamily.
 
    0.579
trpF
N-(5'phosphoribosyl)anthranilate isomerase; Identified by similarity to SP:Q59649; match to protein family HMM PF00697; Belongs to the TrpF family.
 
      0.576
prfB
Peptide chain release factor 2, programmed frameshift; Peptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA.
