|R. Glockshuber, E. Weber-Ban
|Students will carry out defined research projects related to the current research topics of the groups of Prof. Glockshuber and Prof. Weber-Ban. The topics include mechanistic studies on the assembly of adhesive pili from pathogenic bacteria, disulfide bond formation in the bacterial periplasm, ATP-dependent chaperone-protease complexes and formation of amyloid deposits in Alzheimer's disese.
|The course should enable the students to understand and apply biophysical methods, in particular kinetic and spectroscopic methods, to unravel the mechanism of complex reactions of biological macromolecules and assemblies in a quantitative manner.
|The students will be tutored in their experimental work by doctoral or postdoctoral students from the Glockshuber or Weber-Ban group. In addition, the course includes specific lectures that provide the theoretical background for the experimental work, as well as excercises on the numeric evaluation of biophysical data, and literature work.
Participation in one of the following projects will be possible:
Projects of the Glockshuber group:
- Purification, biophysical characterization and structure determiation of enzymes required for disulfide bond formation in the periplasm of Gram-negative bacteria.
- Mechanistic studies on the assembly of type 1 pili from pathogenic Escherichia coli strains. In vitro reconstitution of pilus assembly from all purified components. Characterization of folding, stability and assembly behaviour of individual pilus subunits.
- Identification of intermediates in the aggregation of the human Abeta peptide
Experimental work on these projects involves
- Molecular cloning, recombinant protein production in E. coli and protein purification
- Protein crystallization
- Thermodynamic and kinetic characterization of conformational changes in proteins and protein-ligand interactions by fluorescence and circular dischoism spectroscopy
- Analysis of rapid reactions by stopped-flow fluorescence
- Negative-stain electron microscopy
- Light scattering
Projects of the Weber-Ban group:
- Generation and purification of site-directed variants of the E. coli ClpA/P protease and chaperone-proteasome complexes from other organisms, their biophysical characterization, including rapid kinetics by stopped-flow methods, ATPase activity measurtements, negative-stain electron microscopy and light scattering
|Voraussetzungen / Besonderes
|Marks will be given according to the following criteria:
- Planning, execution and documentation of experimental work
- Final report, including introduction with short overview on the relevant literature, results with figures and brief discussion (maximum: 5 pages)
- Performance in the exercises
|Fundamentals of Biology II: Biochemistry and Molecular Biology
Belegung ist NUR erlaubt für MSc Studierende, die diese Lerneinheit als Auflagenfach verfügt haben.
Alle anderen Studierenden (u.a. auch Mobilitätsstudierende, Doktorierende) können diese Lerneinheit NICHT belegen.
|K. Locher, N. Ban, R. Glockshuber, E. Weber-Ban
|The course provides an introduction to Biochemistry / Molecular Biology with some emphasis on chemical and biophysical aspects.
|Topics include the structure-function
relationship of proteins / nucleic acids, protein folding, enzymatic catalysis, cellular pathways involved in bioenergetics and the biosynthesis and breakdown of amino acids, glycans, nucleotides, fatty acids and phospholipids, and steroids. There will also be a discussion of DNA replication and repair, transcription, and translation.

|Molecular and Structural Biology VI: Biophysical Analysis of Macromolecular Mechanisms
This course is strongly recommended for the Masters Major "Biology and Biophysics".
|R. Glockshuber, T. Ishikawa, S. Jonas, B. Schuler, E. Weber-Ban
|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.
|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".
|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.
|Course material from the individual lecturers wil be made available at the sharepoint website
|Voraussetzungen / Besonderes
|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.
