膜蛋白对其环境进行构象和功能响应的证据正在不断涌现。结构模型必须在蛋白质已从其天然环境中去除的制剂中进行表征。不同的结构方法使用了各种膜模拟物,最近将脂质双层作为更接近天然的环境。应用于脂质双层嵌入整合蛋白的结构工具让我们了解膜蛋白如何响应脂质环境以及其对其他非脂质环境的响应的重要通用特征。在这里,我们回顾了该领域的现状,特别参考了一些经过充分研究的 α-螺旋膜蛋白的观察,作为帮助开发模型细化的可能通用原理的起点。
Evidence that membrane proteins respond conformationally and functionally to their environment is gaining pace. Structural models, by necessity, have been characterized in preparations where the protein has been removed from its native environment. Different structural methods have used various membrane mimetics that have recently included lipid bilayers as a more native-like environment. Structural tools applied to lipid bilayer-embedded integral proteins are informing us about important generic characteristics of how membrane proteins respond to the lipid environment as compared with their response to other non-lipid environments. Here, we review the current status of the field, with specific reference to observations of some well-studied α-helical membrane proteins, as a starting point to aid the development of possible generic principals for model refinement.
