Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

ER Retrieval Pathway

3.8K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Text Mining

Background:

  • The Critical Assessment of Information Extraction systems in Biology (BioCreAtIvE) challenge addresses the need for effective text-mining and information extraction systems in biology.
  • Previous BioCreative workshops highlighted significant challenges with software interoperability and integration complexity in biological text-mining pipelines.
  • Issues included lack of process modularity, OS incompatibility, complex tool configuration, and non-standardized communication protocols.

Purpose of the Study:

  • To evaluate the use of Web services as a solution to mitigate interoperability and integration issues in biological text-mining.
  • To assess the performance of named-entity recognition (NER) Web services for extracting biological terms from scientific literature.
  • To demonstrate how interoperable NER technologies can simplify the implementation of text-mining pipelines for curation groups.

Main Methods:

  • The BioCreative IV challenge, Track 3, focused on named-entity recognition (NER) for the Comparative Toxicogenomics Database (CTD).
  • Participating groups developed Representational State Transfer (REST) / BioC-compliant Web services for NER.
  • CTD evaluated these Web services against a dataset of 510 curated articles, calculating recall, precision, F-scores, and response times.

Main Results:

  • Twelve groups participated, developing NER Web services tailored to CTD's requirements.
  • Top balanced F-scores achieved were 61% for gene, 74% for chemical, and 51% for disease NER.
  • Response times varied significantly, from fractions of a second to over a minute per article.

Conclusions:

  • Web services offer a viable approach to abstract implementation details and improve the integration of NER tools into biological text-mining pipelines.
  • The BioCreative IV challenge demonstrated that interoperable NER technologies can effectively simplify pipeline implementation for curation groups.
  • This facilitates more efficient extraction and utilization of biological information from scientific literature.
