蛋白质结构集成的高效推理

Efficient inference of protein structural ensembles

Thomas J. Lane, Christian R. Schwantes, Kyle A. Beauchamp, Vijay S. Pande

摘要:

越来越清楚的是,传统的蛋白质单一结构模型不足以理解它们的生物学功能。在这里,我们概述了一种从实验中推断蛋白质最常见的结构(天然状态)的方法,但整个系统可以采用的构象。这样的集合模型对于理解内在无序的蛋白质、酶催化和信号传导是必要的。我们认为,生成这样一个模型的最困难的方面将是找到一个小的配置集,以准确地模拟结构异质性,并提出一种方法来克服这一挑战。

英文摘要:

It is becoming clear that traditional, single-structure models of proteins are insufficient for understanding their biological function. Here, we outline one method for inferring, from experiments, not only the most common structure a protein adopts (native state), but the entire ensemble of conformations the system can adopt. Such ensemble mod- els are necessary to understand intrinsically disordered proteins, enzyme catalysis, and signaling. We suggest that the most difficult aspect of generating such a model will be finding a small set of configurations to accurately model structural heterogeneity and present one way to overcome this challenge.
