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:
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 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

Predicted Functional Partners:
nudB
Catalyzes the hydrolysis of dihydroneopterin triphosphate to dihydroneopterin monophosphate and pyrophosphate. Required for efficient folate biosynthesis. Can also hydrolyze nucleoside triphosphates with a preference for dATP
  
  
 0.954
aspS
Catalyzes the attachment of L-aspartate to tRNA(Asp) in a two-step reaction: L-aspartate is first activated by ATP to form Asp- AMP and then transferred to the acceptor end of tRNA(Asp). Also mischarges tRNA(Asp) with D-aspartate, although it is a poor substrate
 
  
 0.928
ruvC
Nuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves the cruciform structure in supercoiled DNA by nicking to strands with the same polarity at sites symmetrically opposed at the junction in the homologous arms and leaves a 5'-terminal phosphate and a 3'-terminal hydroxyl group.
  
  
 0.896
tyrS
Catalyzes the attachment of L-tyrosine to tRNA(Tyr) in a two- step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr) (PubMed:4292198, PubMed:4579631). Can also mischarge tRNA(Tyr) with D-tyrosine, leading to the formation of D-tyrosyl-tRNA(Tyr), which can be hydrolyzed by the D-aminoacyl-tRNA deacylase . In vitro, can also use the non-natural amino acid azatyrosine .

mtfA
Involved in the regulation of ptsG expression by binding and inactivating Mlc
      
 0.561
tsf
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. (Microbial infection) Promotes the tRNase activity of CdiA-CT from E.coli strain EC869 (CdiA-CT-EC869); required in vivo but less so in vitro. Probably loads charged tRNA onto EF-Tu, making more ternary GTP-EF-Tu-aa-tRNA complexes. The guanine nucleotide exchange factor capacity of this protein does not seem to be needed as no GTP hydrolysis occurs during tRNA cleavage. Also required in vivo for toxic ac [...]

fabD
Malonyl CoA-acyl carrier protein transacylase; Enzyme; Fatty acid and phosphatidic acid biosynthesis; Belongs to the FabD family
   
    0.552
rplS
This protein is located at the 30S-50S ribosomal subunit interface. In the 70S ribosome it has been modeled to make two contacts with the 16S rRNA of the 30S subunit forming part of bridges B6 and B8 . In the 3.5 A resolved structures L14 and L19 interact and together make contact with the 16S rRNA . The protein conformation is quite different between the 50S and 70S structures, which may be necessary for translocation.
 
   0.547
lysS
Belongs to the class-II aminoacyl-tRNA synthetase family.
   
  
 0.545
prfB
Peptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA . Acts as a peptidyl-tRNA hydrolase . In the presence of truncated mRNA in the 70S ribosome, ArfA and RF2 interact such that the GGQ peptide hydrolysis motif of RF2 rises into the peptidyl-transferase center and releases the ribosome (PubMed:27906160, PubMed:27906161, PubMed:27934701, PubMed:28077875). Recruited by ArfA to rescue stalled ribosomes in the absence of a normal stop codon (PubMed:22857598, PubMed:22922063, PubMed:25355516). ECO:0000269|PubMe [...]
