The course is directed namely for PhD students specialized on structure analysis of biological materials. It equally fits needs of students in the 4th and 5th year of study. It elucidates the scopes of the protein crystallography allowing analysis of structure and function of biological macromolecules in atomic resolution. Applications of the methodics to drug design form a part of the course. Specialists from different institutes take part in the teaching.
