1 STRUCTURAL BIOINFORMATICS II Spring 2018 Syllabus Course Number - Classification: Chemistry 5412 Class Schedule: Monday 5:30-7:50 PM, SERC Room 456 (4 th floor) Instructors: Ronald Levy, SERC 718 (ronlevy@temple.edu) (course coordinator) Vincenzo Carnevale, SERC 704 (vincenzo.carnevale@temple.edu) Roland Dunbrack, FCCC, (roland.dunbrack@gmail.com) Alan Haldane, SERC 718 (alan.haldane@temple.edu) Office hours: By appointment Description This course is designed to provide a basic introduction to computational methods used in protein structure determination and molecular modeling. The course emphasis will be on the use of computational methods for protein structure prediction to understand protein structures through modelling and on structure based drug design. The course will provide practical training in the application of modeling techniques in drug discovery Objectives The objective of this course is to provide an introductory overview of concepts involved in protein structure determination using homology modelling, molecular simulations, and their role in understanding the physical basis of the structure and function of biological macromolecules. The course is aimed at providing students with a strong grounding in modeling approaches used in drug discovery. Upon successful completion, students are expected to have knowledge of various techniques used for structure determination and acquire skillsets for visualizing and analyzing macromolecular structures. In addition, students will be competent in carrying out basic molecular modelling simulations and be familiarized with structure based drug design strategies and software. Organization Some of the lectures will be held in the computer lab to keep a close connection between theoretical concepts and computational case studies. Most of the computational work will be

2 performed in class; however specific tasks will be completed by the students and evaluated as homework assignments. Materials In addition to the following reference books, additional study materials will be made available in class. Ø Gregory A. Petsko and Dagmar Ringe.
