POPC with varying amounts of cholesterol, 130 mM of NaCl. Slipids with ions by Smith & Dang
<p>Simulations of a POPC bilayer with varying amounts (0, 10, 20, and 30 mol-%) of cholesterol and 130 mM of NaCl performed at 310 K. The POPC bilayer consists of 200 lipids (100 per leaflet) and on top of that there is 0 (0%), 22 (10%), 50 (20%), or 86 (30%) of cholesterol. Additionally, simulations with 0% cholesterol are repeated at 330 K, 350 K, and 370 K. The Slipids model [1–3] is employed for lipids, tip3p model for water, and the ion parameters by Smith and Dang [4] for NaCl. The Slipids force field parameters are available at http://www.fos.su.se/~sasha/SLipids/ and the ion parameters are available at https://bitbucket.org/hseara/ions/</p> <p>––––––––––––––––––––––––––––––––––––––––––––––––––––––</p> <p>The files are in GROMACS format and named based on the amount of cholesterol present (in %) in the corresponding simulation. Trajectories (.xtc) are 200 ns long with data saved every 100 ps. Additionally, the final structure (.gro), topology (.top), index file (.ndx), energy output file (.edr), and binary run input files (for Gromacs 4.6->) (.tpr) are provided for each system. The common simulation parameter file can be downloaded from another entry at https://doi.org/10.5281/zenodo.259341.</p> <p>––––––––––––––––––––––––––––––––––––––––––––––––––––––</p> <p>[1] Derivation and Systematic Validation of a Refined All-Atom Force Field for Phosphatidylcholine Lipids.
