Aim
The course aims at giving the student:
- molecular-level understanding of the structure, stability, interactions and dynamics of proteins.
- knowledge about the principal physical methods used in modern protein science.
- practical experience in using some of these methods.
- the knowledge base needed to use and critically assess the protein research literature.
Learning outcomes
Knowledge and understanding
For a passing grade the student must
- describe the principal physico-chemical properties of proteins, such as structure, stability, interactions and dynamics.
- account for these properties in terms of molecular-level theroetical models.
- interpret experimental results from physico-chemical studies of proteins.
Competences and skills
For a passing grade the student must
- use physico-chemical concepts and models to solve problems involving proteins.
- apply his/her theoretical knowledge to biotechnological and biomedical problems.
- use electronic protein databases.
- carry out spectroscopic measurements on proteins.
Judgement and approach
For a passing grade the student must
- read and critically assess research literature in protein science.
- communicate effectively with researchers in protein science.
Contents
The course addresses the following main topics:
- The chemical building-blocks and three-dimensional structures of proteins: Structure analysis by X-ray crystallography; Structure and sequence databases; Bioinformatics.
- Protein characterization by optical spectroscopy: Physical principles and applications of fluorescence and circular dichroism spectroscopy.
- Polypeptide conformation: Models of polymer conformation and conformational transitions; Conformational entropy; Folding cooperativity.
- Protein energetics and stability: Packing; Hydration; Electrostatics; Thermal and solvent-induced denaturation; Differential scanning calorimetry.
- Protein dynamics: Kinetic models; Proton exchange; Diffusion control; Protein folding; Computer simulation of proteins.
- Nuclear magnetic resonance: Principles of NMR spectroscopy and relaxation; Analysis of structure, interactions and dynamics of proteins in solution.
- Association processes: Ligand binding; Allostery; Protein aggregation; Isothermal titration calorimetry; Surface plasmon resonance.
Examination details
Grading scale: TH - (U, 3, 4, 5) - (Fail, Three, Four, Five)
Assessment: The final grade is based on weekly take-home problem assignments (50%) and a written midterm exam (50%). Approved laboratory practicals and oral presentation are needed for a passing grade. If necessary, reexamination (of the midterm exam) will be performed orally.
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
