Advances in coarse-grained molecular dynamics (CGMD) simulations have extended the use of computational studies on biological macromolecules and their complexes, as well as the interactions of membrane protein and lipid complexes at a reduced level of representation, allowing longer and larger molecular dynamics simulations. Here, we present a computational platform dedicated to the preparation, running, and analysis of CGMD simulations. The platform is built on a completely revisited version of our (MERMAID) web server, and it integrates this with other three dedicated services. In its current version, the platform expands the existing implementation of the Martini force field for membrane proteins to also allow the simulation of soluble proteins using the Martini and the SIRAH force fields. Moreover, it offers an automated protocol for carrying out the backmapping of the coarse-grained description of the system into an atomistic one.
粗粒化分子动力学(CGMD)模拟的进展扩展了计算研究在生物大分子及其复合物,以及膜蛋白和脂质复合物相互作用方面的应用,其代表了一种在简化水平上的模拟,使得更长和更大的分子动力学模拟成为可能。在这里,我们介绍了一个专门用于准备、运行和分析 CGMD 模拟的计算平台。该平台建立在我们完全重新设计的(MERMAID)网络服务器版本之上,并将其与其他三个专用服务集成在一起。在其当前版本中,该平台扩展了现有的用于膜蛋白的 Martini 力场的实现,也允许使用 Martini 和 SIRAH 力场模拟可溶性蛋白质。此外,它还提供了一种自动协议,用于将系统的粗粒化描述映射回原子级描述。
