The functional activity of membrane proteins is carried out in a complex lipid environment. Increasingly, it is becoming clear that lipids are an important player in regulating or generally modulating their activity. A routinely used method to gain insight into this interplay between lipids and proteins are Molecular Dynamics (MD) simulations, since they allow us to study interactions at atomic or near-atomic detail as a function of time. A major bottleneck, however, is analyzing and visualizing lipid-protein interactions, which, in practice, is a time-demanding task. Here, we present ProLint (www.prolint.ca), a webserver that completely automates analysis of MD generated files and visualization of lipid-protein interactions. Analysis is modular allowing users to select their preferred method, and visualization is entirely interactive through custom built applications that enable a detailed qualitative and quantitative exploration of lipid-protein interactions. ProLint also includes a database of published MD results that have been processed through the ProLint workflow and can be visualized by anyone regardless of their level of experience with MD. The automated analysis, feature-rich visualization, database integration, and open-source distribution with an easy to install process, will allow ProLint to become a routine workflow in lipid-protein interaction studies.
膜蛋白的功能活动是在复杂的脂质环境中进行的。越来越明显的是,脂质是调节或普遍调节其活性的重要参与者。分子动力学(MD)模拟是一种常用的方法,可以深入了解脂质和蛋白质之间的相互作用,因为它们允许我们随着时间的推移研究原子或近原子细节的相互作用。然而,分析和可视化脂质-蛋白质相互作用是一个主要的瓶颈,在实践中,这是一项耗时的任务。在这里,我们介绍了 ProLint(www.prolint.ca),这是一个网络服务器,它可以完全自动化分析 MD 生成的文件和可视化脂质-蛋白质相互作用。分析是模块化的,允许用户选择他们喜欢的方法,可视化是完全交互式的,通过自定义构建的应用程序,可以对脂质-蛋白质相互作用进行详细的定性和定量探索。ProLint 还包括一个已通过 ProLint 工作流程处理的已发表 MD 结果数据库,任何人都可以通过该数据库进行可视化,无论他们对 MD 的经验水平如何。自动化分析、功能丰富的可视化、数据库集成以及带有易于安装过程的开源分发,将使 ProLint 成为脂质-蛋白质相互作用研究中的常规工作流程。
