Preparing Membrane Proteins for Simulation Using CHARMM-GUI.
Abstract
Molecular dynamics simulations of membrane proteins have grown dramatically in the last 20\xa0years. Running these simulations first requires embedding the protein s three-dimensional structure in a lipid bilayer of a suitable composition, one that resembles its native environment. This step is far from trivial, especially for modeling heterogeneous mixtures of lipids. CHARMM-GUI, a webserver for simulation system preparation greatly simplifies this step, allowing for the construction of complex heterogeneous and/or asymmetric membranes. Here, we demonstrate how to use CHARMM-GUI to build the membrane for the outer-membrane protein BamA.
