本文综述了构象系综在生物分子动力学、分子识别和变构分析中的作用。我们介绍了目前可用的方法产生的生物分子的合奏,并说明其应用与相关的文献中的例子。我们展示了如何结合,构象合奏提供了一种区分诱导适合和构象选择的竞争模型。对于变构,我们回顾了经典的模型,并展示了构象系综如何在解开使变构发生的错综复杂的通信途径中发挥作用。最后,我们讨论了构象系综的局限性,并强调了未来的一些潜在应用。
We review the role conformational ensembles can play in the analysis of biomolecular dynamics, molecular recognition, and allostery. We introduce currently available methods for generating ensembles of biomolecules and illustrate their application with relevant examples from the literature. We show how, for binding, conformational ensembles provide a way of distinguishing the competing models of induced fit and conformational selection. For allostery we review the classic models and show how conformational ensembles can play a role in unravelling the intricate pathways of communication that enable allostery to occur. Finally, we discuss the limitations of conformational ensembles and highlight some potential applications for the future.
