Course Description

Biomolecular Simulations

Program

Nanosciences and Nanotechnologies, third-level study programme

Lecturers:

doc. dr. Janez Mavri

Goals:

Students will gain insight into the problems of intermolecular simulations: quantum-mechanical methods, molecular mechanics-based methods enabling thermal averaging, the modelling of chemical reactions in solutions, enzymatic reactions and the planning of inhibitors. Practical work involving the use of computers constitutes an integral part of this course.

Content:

· Time-dependent and time-independent Schrödinger equation
· Force field
· Chemical reactions in the gas phase
· Molecular dynamics and the Monte Carlo simulation
· Refinement: Incorporation of experimental data
· How to calculate free energy differences
· Chemical reaction in an enzymatic environment
· Simulation of tunnelling: the Born-Oppenheimer approximation
· Design of inhibitors on the basis of the transition-state structure
· Model study i) proton dynamics in the apoenzyme of HIV-1 protease
· Model study ii) Irreversible inhibition of HIV-1 protease
· Model study iii) Carcinogenesis caused by aromatic substances
· Future of biomolecular simulations
