Advanced Magnetic Resonance - Biological Magnetic Resonance
Last Updated: 2026-06-01 11:30:42
Abstract
The course is for advanced students and covers selected topics from magnetic resonance spectroscopy. It is concerned with inference of structure and dynamics of proteins and their complexes from data obtained by EPR and liquid-state NMR experiments. The special focus is on multi-state and ensemble modelling.
Objective
This course enables students to design experimental strategies for characterization of structure and dynamics of proteins whose flexibility is relevant for their function. Students understand the spin dynamics that encodes sidechain and backbone motion as well as distance information into signals measured by magnetic resonance experiments. They learn to solve the inverse problem of inferring dynamics parameters and distances from the experimental results. They acquire skills in modelling protein ensemble structure from constraints derived by analyzing magnetic resonance data. Students are aware of the complications introduced by the use of spin labels in such experiments and learn how to include such labels in modelling.
Content
• Nitroxide spin labels, their interaction with the environment, and influence of their dynamics on EPR line shapes • Contributions to electron spin decoherence and ways to improve resolution in pulsed EPR • Measurement of electron-electron dipole-dipole interaction and conversion of the primary data to distance distributions • Modelling of spin labels by rotamer libraries • Ensemble modelling with distance distributions • Liquid-state NMR experiments for assessing protein structure and dynamics • Assignment of NMR signals for proteins • Theory of the nuclear Overhauser effect (NOE) • Ensemble modelling with exact NOE constraints • Multistate structure calculation and analysis • Further constraints on protein structure and dynamics from NMR experiments
