STRUCTURE BIOSYNTHESIS AND ANALYSIS OF PROTEINS

Course objectives

General aims This course aims to lead students to a deeper knowledge on folds and folding of proteins and protein complexes, to enable them to present/disseminate/discuss specific protein structure-function relationships, and to introduce them to current knowledge on "molecular machines”. Specific aims • Preliminary knowledge Basic notions of protein structure (indispensable), molecular biology (indispensable), genetics (important) and cellular biology (important) • Knowledge of the student at the end of the course: Students will acquire knowledge of the complex dynamic events that bring the newly formed polypeptides to assume 3D structures and biological functions, and will familiarize with the main methodologies in protein structure determination. • Acquired skills of the student with this course: At the end of the course, students will be able to query protein 3D databases, and to create publication quality images and movies by molecular graphics. • Critical and judgmental skills acquired at the end of the course: Students will know how to discuss in depth structure-function relationships of specific proteins, to interpret in a structural key the biological consequences of genetic mutations, and to address the design of modified protein structures. • Communication skills on course content: The final assessment intends to evaluate acquired knowledge, but also student skills in the use of molecular graphic programs, both in research and in result dissemination. • Ability to continue independently From the knowledge of the addressed topics, students will have acquired the cultural background and the prerequisite skills to face a wide range of Protein Biochemistry issues.

Course program
Basics of protein structure and biosynthesis. Structure/function relationships of the main alpha helix-, beta sheet-, alfa/beta- and alfaANDbeta-rich folds (associative principles between secondary structural units, connectivity, turns and loops, principles of protein topology) and selected examples of biological relevance. Notes on protein folding in vitro and in vivo. Main techniques in determination and prediction of protein 3D structure, in analysis and simulation of protein folding, and in characterization of protein-protein interactions. Structure/function relationships in specific protein systems (membrane proteins, multienzymatic complexes, metalloproteins).
Prerequisites
Basic knowledge of protein biochemistry and molecular biology is required; basic knowledge of genetics and cellular biology is important.
Books
The text book is M. Williamson 'Come funzionano le proteine' ed. Zanichelli. Other materials are published at the educational site Elearning2 at http://elearning2.uniroma1.it
Teaching mode
Classroom lectures (20 lessons) and learning activities (12 hours)
Frequency
Lectures and guided activities are not mandatory. For students not attending the lectures, a self-assessment test on minimum knowledge and copies of all lectures will be uploaded at the eLearning page of the course.
Exam mode
In the final evaluation, through a practical test, students will be evaluated on their skills both of using protein 3D structure databases and molecular graphics programs for describing a protein system of their choice. Originality and skills in using the molecular graphics will be specifically considered in final evaluation. Whenever both objectives will be achieved, 25 will be the starting mark. Following a further discussion on a molecular detail of the chosen protein system, the evaluation of the student’s body of knowledge on protein folding and of a proper terminology, will complete the final evaluation increasing marks up to 30.
