Significance for science
New developments in molecular dynamics integration methods can find wide applications in computer simulations of the structure and dynamics of biological macromolecules in contributing to higher precision and economy of computation. The new methods use less computer time and therefore extend the applicability of simulation strategies to larger systems and enable higher precision calculations. A particularly promising consequence of the enhanced possibilities offered by the new methods is the inclusion of solvent effects. This requires a major computational effort in present schemes, thus strongly limiting the number of solvent molecules that can be included in the simulation. The new methods should therefore highly improve on this important aspect of molecular simulations. From the practical point of view, protein engineering should benefit from the predicting capacity of the molecular dynamics simulation methods that would become more economical. Since protein engineering is a promising area of development in at least two institutes in Slovenia, the benefit of this research is obvious. The development of molecular dynamics algorithms as presented can be included as a software module in computer programs commonly used for molecular modeling of biological systems. The ability to improve the predicting power of methods used in the simulation of proteins is of paramount importance for protein engineering and is sealing the relation between the higher order structure of proteins and their biological function. The research carried out following this proposal is of great importance to the development of modern simulation techniques that hold the promise to greatly increase our ability to simulate large macromolecular systems with a reasonable amount of computational effort. It is expected that the product of this research effort will be added to the CHARMM (Chemistry at HARvard for Macromolecular Mechanics) program and distributed for use by others throughout the world.
Significance for the country
The purpose of the project is to develop, improve, and apply the computational methods for molecular dynamics simulations in the study of the structure and dynamics of biological macromolecules, such as proteins. The project focuses on specific problems of molecular biology, on code development and application, and also on its parallel implementation. An important component of the project involves close collaboration with the leading laboratories in this research field. The results of this research were published in international scientific journals and were presented at international scientific meetings. In collaboration between the Center for Molecular Modeling from the National Institute of Chemistry and Lek, a new Sandoz company, Drug Discovery we apply computer simulations to novel chemical entities (NCE's) in the antiinfective and cardiovascular therapeutic areas. We collaborate also with groups from the IJS, MF, FMF, BF, FF, FRI ( UL), and FAMNIT (UP). In collaboration with Lek, a new Sandoz company, Drug Discovery the Laboratory for Molecular Modeling is involved in several industrial projects that use molecular modeling methods for research into new drug leads. Industrial project for LEK, d.d., contract: Computer modeling of biopharmaceutical molecules bt web server ProBiS. PI: Prof. Dr. Dušanka Janežič.
