| Outline of Final Research Achievements |
Accurate structural superposition is a necessity for studying static and/or dynamic structures of proteins. In this study, we developed a theoretical framework for structural superposition that concerns occupancy factors in crystal structures and off-diagonal components of covariance matrices. The method was implemented as a computer program, mmfitc. It is useful for analyzing, for example, molecular dynamics data, where a great number of structures are subject to. For superposition, we also developed another method which is insensitive to outlier protein molecules to some extent. The method is useful for superposition of a moderate number of structures such as in the case for comparing the crystal structures.
