Abstract
The main goal of the proposed research project is to provide a new computational tools for simulating and analysing low frequency collective motions of biomolecules including: i) lattice- and internal-vibrations of molecular crystals, and ii) large-scale motions involved during configurational changes such as domain motions, aggregation and oligomerization, structural phase transitions... The developed methods and computer packages will allow inelastic neutron and X-ray scattering observables to be calculated from atomic detail models, allowing comparison with- and interpretation of- experimental data produced at large scale experimental facilities (DNA). Various simplification schemes will be presented for analysing displacement vectors, which are otherwise too complicated to recognize characteristic motions in very large systems. Using »principal component analysis« we aim to identify the form and tendency of configurational changes during the oligomerization process (i.e. during amyloid formation) and construct the molecular dynamics simulation method based on additional steering forces acting along selected principal components in order to speed up the detected configurational change.
The proposed approaches will open the door to a general understanding of many dynamically- driven processes involved in biomolecular systems.
Significance for science
The developed methods present new efficient solutions of problems in the field of biomolecular simulations. The methods are built-in into existing simulation program packages, providing the availability of the moetgods to the wider range of researchers. Our methods present contribution to in improving the prediction power of biomolecular
simulations.
Significance for the country
Within the project we collaborate with the leading institutions in the field, like institute ILL in Grenoble and University of Heidelberg, which strengthens our international connections. Besides, we get a chance to access the instruments for neutron scattering in ILL. The developed methods are made available to the users, in particular to Phd studens studying at different natural-science faculties.
