551-1402-00L | Molecular and Structural Biology VI: Biophysical Analysis of Macromolecular Mechanisms This course is strongly recommended for the Masters Major "Biology and Biophysics". | 4 credits | 2V | R. Glockshuber, T. Ishikawa, S. Jonas, B. Schuler, D. Veprintsev, E. Weber-Ban | |
Abstract | The course is focussed on biophysical methods for characterising conformational transitions and reaction mechanisms of proteins and biological mecromolecules, with focus on methods that have not been covered in the Biology Bachelor Curriculum. | ||||
Learning objective | The goal of the course is to give the students a broad overview on biopyhsical techniques available for studying conformational transitions and complex reaction mechanisms of biological macromolecules. The course is particularly suited for students enrolled in the Majors "Structural Biology and Biophysics", "Biochemistry" and "Chemical Biology" of the Biology MSc curriculum, as well as for MSc students of Chemistry and Interdisciplinary Natural Sciences". | ||||
Content | The biophysical methods covered in the course include advanced reaction kinetics, methods for the thermodynamic and kinetic analysis of protein-ligand interactions, static and dynamic light scattering, analytical ultracentrifugation, spectroscopic techniques such as fluorescence anisotropy, fluorescence resonance energy transfer (FRET) and single molecule fluorescence spectrosopy, modern electron microscopy techniques, atomic force microscopy, and isothermal and differential scanning calorimetry. | ||||
Lecture notes | Course material from the individual lecturers wil be made available at the sharepoint website https://team.biol.ethz.ch/e-learn/551-1402-00L | ||||
Prerequisites / Notice | Finished BSc curriculum in Biology, Chemistry or Interdisciplinary Natural Sciences. The course is also adequate for doctoral students with research projects in structural biology, biophysics, biochemistry and chemical biology. | ||||
551-1412-00L | Molecular and Structural Biology IV: Visualizing Macromolecules by X-Ray Crystallography and EM | 4 credits | 2V | N. Ban, D. Böhringer, T. Ishikawa, M. A. Leibundgut, K. Locher, M. Pilhofer, K. Wüthrich, further lecturers | |
Abstract | This course provides an in-depth discussion of two main methods to determine the 3D structures of macromolecules and complexes at high resolution: X-ray crystallography and cryo-electron microscopy. Both techniques result in electron density maps that are interpreted by atomic models. | ||||
Learning objective | Students will obtain the theoretical background to understand structure determination techniques employed in X-ray crystallography and electron microscopy, including diffraction theory, crystal growth and analysis, reciprocal space calculations, interpretation of electron density, structure building and refinement as well as validation. The course will also provide an introduction into the use of cryo-electron tomography to visualize complex cellular substructures at sub-nanometer resolutions, effectively bridging the resolution gap between optical microscopy and single particle cryo-electron microscopy. Lectures will be complemented with practical sessions where students will have a chance to gain hands on experience with sample preparation, data processing and structure building and refinement. | ||||
