A practical introduction to molecular dynamics simulations: Applications to homology modeling

Abstract

In this chapter, practical concepts and guidelines are provided for the use of molecular dynamics (MD) simulation for the refinement of homology models. First, an overview of the history and a theoretical background of MD are given. Literature examples of successful MD refinement of homology models are reviewed before selecting the Cytochrome P450 2J2 structure as a case study. We describe the setup of a system for classical MD simulation in a detailed stepwise fashion and how to perform the refinement described in the publication of Li et al. (Proteins 71:938-949, 2008). This tutorial is based on version 11 of the AMBER Molecular Dynamics software package ( http://ambermd.org/ ). However, the approach discussed is equally applicable to any condensed phase MD simulation environment. © 2011 Springer Science+Business Media,LLC.
