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

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. (188 aa)    
Predicted Functional Partners:
fin
Protein required for the switch from F to G during sporulation (anti sigma F); An anti-sigma factor for sporulation specific sigma-F factor, by antagonizing sigma-F it allows the switch to sigma-G factor and progression to the late sporulation development stages. Might stabilize or process Holliday junction intermediates, although this may be due to polar effects on the downstream mfd gene.
  
    0.921
engD
Putative GTPase with RNA binding site; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family. YchF/OLA1 subfamily.
 
  
 0.903
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 N-terminal section; belongs to the UvrB family.
  
  
 0.899
ctc
Ribosomal protein Ctc, binding 5S RNA; Not required for exponential growth; probably functions in vegetatively growing cells, maybe required for accurate translation under stress conditions.
 
  
 0.884
dsdA
D-serine ammonia-lyase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the serine/threonine dehydratase family. DsdA subfamily.
 
      0.862
prfB
Peptide chain release factor 2; Peptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA.
 
  
 0.822
tilS
tRNAile lysidine synthetase; Ligates lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine. Belongs to the tRNA(Ile)-lysidine synthase family.
 
  
 0.785
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.
 
   
 0.741
ybbK
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
      0.713
rpmA
Ribosomal protein L27 (BL24); Plays a role in sporulation at high temperatures.
