分子动力学 (MD) 模拟方法和可用计算资源的最新进展使得对生物现象的模拟变得更加可靠。通过全原子 MD 模拟,我们现在能够详细地可视化抗菌肽 (AMP) 和各种膜模拟物之间的相互作用。这有助于我们了解抗菌活性和毒性的分子机制。本章介绍如何设置和进行 AMP 和膜模拟物的分子动力学模拟。详细介绍了用于研究 AMP 的感兴趣系统的构建,其中包括模拟水、胶束或脂质双层中的肽。还提供了运行模拟所需参数的说明。
Recent advances in molecular dynamics (MD) simulation methods and in available computational resources have allowed for more reliable simulations of biological phenomena. From all-atom MD simulations, we are now able to visualize in detail the interactions between antimicrobial peptides (AMPs) and a variety of membrane mimics. This helps us to understand the molecular mechanisms of antimicrobial activity and toxicity. This chapter describes how to set up and conduct molecular dynamics simulations of AMPs and membrane mimics. Details are given for the construction of systems of interest for studying AMPs, which can include simulations of peptides in water, micelles, or lipid bilayers. Explanations of the parameters needed for running a simulation are provided as well.
