Prerequisites: Basics of mathematics, physics and biochemistry.
Target skills and knowledge: The course provides the cultural elements for the investigation of the structure-function relationship in proteins, nucleic acids and their complexes in a molecular approach to the understanding of natural processes. The principal methods for purification and characterization of proteins and conventional and advanced spectroscopic techniques will be considered.
Examination methods: Part A
Written examination with general questions and numerical exercises
Part B
Oral Exam

Evaluation of reports on laboratory experiments
The assessment is weighted on the written/oral exam for 75% and on laboratory reports for 25%. The final mark is the average of the outcomes relating to the two parts, A and B
Assessment criteria: Ability to identify methods of investigation, and use them properly, among those provided as part of the course, to solve any specific problem related to purification and structural-functional characteristics of macromolecules.
Capacity to present, discuss and rationalize data relative to the laboratory experience.
The student will be evaluated based on the level of learning, awareness, ability to reflect and critically discuss the specific skills of the discipline.
Course unit contents: Part A
The course provides the description of biochemical and biophysical techniques used in the study of soluble and membrane proteins, nucleic acids and their complexes, according to the following scheme:
- UV-Vis Absorption Spectroscopy- applications to the study of proteins, cofactors, coenzymes, metalloproteins and nucleotides. Time resolved techniques: applications to the study of enzyme kinetics of electron transfer reactions in proteins and in particular in photosynthesis.
- Techniques using fluorescent probes: fluorescence and fluorescence quenching, fluorescence anisotropy, Energy transfer and FRET (Fluorescence Resonance Energy Transfer), imaging, immunofluorescence; FRAP. Application to biological systems.
- Circular dichroism principles and applications in the field of protein conformation. Determination of protein secondary structure, determination of structural changes induced bu stimulus(for ex. pH, heat, solvent, substrates; studies of folding / unfolding; studies of ligand binding, protein-protein a.d protein-nucleic acids interactions.

Part B
- Introduction to protein purification.
- Principles of chromatographic techniques for proteins: van Deemter equation, efficiency, selectivity and resolution.
- Separation techniques based on macromolecule activity: affinity chromatography (AC).
- Separation techniques based on dimensions: size-exclusion chromatography (SEC).
- Separation techniques based on charges: anion and cation exchange, weak and strong exchangers.
- Separation techniques based on hydrophobicity: hydrophobic interaction and reverse-phase (RP) chromatography.
- Protein stability: conformational stability of proteins; stabilizing interactions in proteins; thermodynamics of the native/denatured transition in proteins.
- Thermodynamic methods for protein characterization: overview of bio-calorimetry (DSC and ITC).
- Hydrodynamic and aggregation properties of proteins in solution: static and dynamic light scattering methods.
- Purification, bio-calorimetry and light scattering applications to proteins.
Planned learning activities and teaching methods: Lectures accompanied by slides
Laboratory experience to be defined each year
