Programma
Teaching Unit of Structural Analysis (3 CFU)
This teaching module is focused on the 3D structure determination of proteins by using biocrystallographic techniques. The method for structure determination through X-ray diffraction will be analyzed, with emphasis on the experimental techniques for protein crystal growth, and on the basic principles of X-ray diffraction: X-ray sources, synchrotron light, atomic scattering factors, structure factors, the "phase problem", phasing by molecular replacement and heavy atoms. Protein model refinement and validation techniques will be analyzed, together with the basic concepts and contents of the Protein Data Bank.
Teaching unit of Form Advanced Enzymology (3 CFU)
General aim of the teaching unit is to increase students' understanding of enzyme properties, building on the bases provided by the first-level degree in Biological Sciences. The following topics will be covered: Enzyme reaction mechanisms and related rate equations under steady-state conditions. One- and two-substrate reactions. Reversible enzyme reactions. Techniques for the study of steady-state phase of enzyme reactions. Enzyme assays. Measurement of enzyme kinetic parameters. Enzyme inhibition. Experimental design and interpretation of results in the kinetic study of enzyme reactions. Protein engineering for the study of structure-function relationships in enzymes at the molecular level.
