Outline of Final Research Achievements |
A computational method that can predict both the complex structure and the affinity between proteins such as antigen-antibody with high speed and accuracy has been developed. This method is composed of decoy generation by rough docking, followed by ranking of the decoys using the free-energy obtained from molecular dynamics simulation as a scoring function. We applied this method to PPARγ, which revealed that as the ligand dissociates, it passes near R288. Decoy sets of hemagglutinin-antibody and adenosine receptor-antibody were ranked by GB/SA scoring, where the near-native decoy was ranked within top 2. The binding free-energy calculation of hemagglutinin-antibody reproduced the experimental value better in comparison with the GB/SA method.
