^{(*)}The lectures are concerned with the subject of theoretical research of the structure, function and dynamics of molecules. Students will become familiar with the following topics: various computer representations of molecular structures, searching in structural databases, the acquisition of protein structural parameters, a brief overview of structurebased methods of energy computation, homology modelling and energy minimisationbased modelling, molecular dynamics, proteinligand interactions, prediction of protein structure and docking of ligands. The course also includes practical exercises concerning visualisation, modification and structure based computations on real molecular systems. Recommended literature, demonstration and application software will be available during the course.
