Short Description
The course introduces the principles of protein structure determination by X-ray crystallography (protein crystallography). Following a condensed introduction (or recapitulation) to the physical basics of crystallography, the procedure for elucidating a protein structure from protein crystals will be explained. Practical training by applying public domain software to selected examples will facilitate the acquisition of concepts and the problems associated with crystallographic model building.
Learning Objectives

Students will know the physical principles of X-ray crystallography for protein structure determination. They will understand the process of solving protein structures from the crystallisation to structural refinement. They will understand the crystallographic model building process as a reconstruction, along with the limitations associated with the method. Students will be capable of using public domain software tools for assessing the quality of protein structure models for use in, for example, computer-aided drug discovery.
