310102 VO Angewandte Makromolekulare Kristallographie (2006S)

Credit-points: 4
Kommentar: During this course students will be introduced to modern methods of
macromolecular X-ray crystallography.
The following topics will be covered:
* sources of X-rays
* crystallisation techniques
* symmetry (point groups, space groups), unit cell, Bravais lattice
* scattering of X-rays, atomic form factor, structure factor
* waves, diffraction on molecules and crystals, Fourier transform; electron density
* set-up of MX diffraction experiment and detectors
* methods for solution of phase problem: molecular replacement, multiple isomorphous replacement, multi-wavelength anomalous dispersion
* density modification techniques
* structure refinement and structural analysis.
