New numerical criteria assess protein structure prediction methods. These criteria, developed after the first Critical Assessment of methods for protein Structure Prediction (CASP1), were evaluated in CASP2 for comparative modeling effectiveness.

Area of Science:

  • Computational biology
  • Structural bioinformatics
  • Protein structure prediction

Background:

  • The Critical Assessment of methods for protein Structure Prediction (CASP) initiative benchmarks protein structure prediction methods.
  • CASP1 highlighted the need for standardized performance evaluation criteria.

Purpose of the Study:

  • To report numerical criteria for assessing comparative modeling in protein structure prediction.
  • To evaluate the effectiveness of these criteria in the CASP2 experiment.
  • To establish a comprehensive and evolving assessment of comparative modeling quality.

Main Methods:

  • Development of numerical criteria specifically for comparative modeling.
  • Application and analysis of these criteria during the CASP2 assessment.
