autumn 2016
KJE-3403 X-ray Crystallography 1 - 10 ECTS

Application deadline

Applicants from Nordic countries: 1 June for the autumn semester and 1 December for the spring semester. Exchange students and Fulbright students: 1 October for the spring semester and 15 April for the autumn semester.

Type of course

Theoretical and practical subject. The course is available as a singular or elective course independent of study program, also to exchange students. The course is offered on condition that a minimum number of students register for the course.

Admission requirements

Students should have basic knowledge in chemistry (atomic and molecular structure), biochemistry (protein structure), and mathematics (calculus). Basic knowledge in physics (electromagnetic radiation, wave mechanics) is recommended.

Course overlap

If you pass the examination in this course, you will get an reduction in credits (as stated below), if you previously have passed the following courses:

K-340 X-ray crystallography 10 stp
KJE-8403 Crystallography I 10 stp
KJE-8703 BIOSTRUCT - Crystallization of biological macromolecules 3 stp

Course content

Starting in 1901, and including 2003, 2006, 2009, 2011, and 2012, more than 15 scientific Nobel Prizes have substantially advanced or involved X-ray crystallography and its ability to determination the three dimensional structures of molecules of any size at atomic resolution. This reflects the central role crystallography continues to play in revealing the structural origins of molecular properties, enabling practical applications ranging broadly, from semiconductor design to drug discovery.

This course gives students both a theoretical foundation of, and practical experience with, modern crystallography. The content involves both theory and experiment, spanning technologies from the generation of X-rays and crystallization of compounds and macromolecules to the determination and evaluation of their molecular structures. Lectures are accompanied by a one week intensive course in crystallization and a research project designed to complement the student's research interests.

The course will be presented in 3 sections: (i) Practical and theoretical introduction to methods for the crystallisation of small molecules and biological macromolecules. (3 credits). (ii) Basic crystallography, diffraction and the measurement and processing of diffraction data. (4 credits). (iii) Structure determination. (3 credits).

The first section of the course can be offered as a separate unit of 3 credits.


Objectives of the course

The candidate will acquire a solid and broad theoretical and practical basis to understand and perform modern crystallographic structure determination. This will be accompanied by focussed topical studies a from practical lab project in crystallization and an additional project, either experimental or computational, chosen to match specific research interests and goals of the student.
