Transmembrane protein models based on high-throughput molecular dynamics simulations with experimental constraints.
Elucidating the structure of transmembrane proteins domains with high-resolution methods is a difficult and sometimes impossible task. Here, we explain the method of combining a limited amount of experimental data with automated high-throughput molecular dynamics (MD) simulations of alpha-helical transmembrane bundles in an explicit lipid bilayer/water environment. The procedure uses a systematic conformational search of the helix rotation with experimentally constrained MDs simulations. The experimentally determined helix tilt and rotational angle of a labeled residue with site-specific infrared dichroism allows us to select a unique high-resolution model from a number of possible energy minima encountered in the systematic conformational search.
