Simulations of a POPC bilayer with 450 mM of CaCl_2. <br> The goal was to study the effect of salt on the order <br> parameters of the lipid head group and the glycerol <br> backbone for the NMRlipids project, see <br> http://nmrlipids.blogspot.fi for more information. A POPC bilayer consisting of 200 lipids (100 per leaflet) <br> is simulated in the presence of 450 mM CaCl_2. The Slipids <br> model [1–3] is employed for lipids, tip3p model for water, <br> and the default amber ion parameters (type C0) for CaCl_2. The Slipids force field parameters were downloaded from<br> http://mmkluster.fos.su.se/slipids/ –––––––––––––––––––––––––––––––––––––––––––––––––––––– The files are in GROMACS format. Trajectory (.xtc) is <br> 100 ns long with data saved every 100 ps. These data<br> were collected after 1900 ns of simulation. Additionally, the initial structure (.gro), topology (.top), index file (.ndx), <br> simulation paremeter file (.mdp), binary run input file <br> for GROMACS v. 4.6–&gt; (.tpr) and the energy output file <br> (.edr) are provided. –––––––––––––––––––––––––––––––––––––––––––––––––––––– [1] Derivation and Systematic Validation of a Refined <br> All-Atom Force Field for Phosphatidylcholine Lipids<br> Joakim P.

本数据集为含450 mM氯化钙(CaCl₂)的1-棕榈酰-2-油酰-sn-甘油-3-磷酸胆碱(POPC)双层膜模拟体系。本研究旨在为NMRlipids项目探究盐浓度对脂质头部基团及甘油骨架有序参数的影响,更多信息可访问http://nmrlipids.blogspot.fi。 本模拟体系包含200个POPC分子(双分子层的每个单层各100个),在450 mM CaCl₂环境下开展模拟。脂质体系采用Slipids力场[1–3],水分子采用tip3p模型,CaCl₂则使用Amber默认离子参数(类型C0)。Slipids力场参数可从http://mmkluster.fos.su.se/slipids/下载获取。 –––––––––––––––––––––––––––––––––––––––––––––––––––––– 本数据集所有文件均采用GROMACS格式。轨迹文件(.xtc)时长为100 ns,每100 ps保存一组数据,所有采集数据均来自模拟运行1900 ns之后的阶段。此外还提供了初始结构文件(.gro)、拓扑文件(.top)、索引文件(.ndx)、模拟参数文件(.mdp)、适用于GROMACS 4.6及以上版本的二进制运行输入文件(.tpr)以及能量输出文件(.edr)。 –––––––––––––––––––––––––––––––––––––––––––––––––––––– [1] 《精修的全原子力场用于磷脂酰胆碱脂质的推导与系统验证》,约阿基姆·P·M·耶姆贝克(Joakim P.
