1071-蛋白质能量景观的大规模发现、分析与设计
from 聊聊Sci
这篇论文介绍了一种名为多路复用氢氘交换质谱(mHDX-MS)的新型实验技术,旨在大规模探索蛋白质的能量景观。研究团队通过该方法同时分析了超过5,000个蛋白质结构域,成功揭示了蛋白质在折叠态与高能激发态之间波动的规律。实验数据表明,即使是具有相似拓扑结构和全局稳定性的蛋白质,其构象波动也存在显著差异。通过结合机器学习和计算建模,科学家们识别出了影响能量景观的关键结构因素,并实现了对蛋白质局部稳定性的精准设计。这项突破性工作不仅弥补了传统结构生物学难以观测稀有瞬态的缺陷,还为开发预测蛋白质动态属性的人工智能模型提供了海量数据支撑。References:Ferrari Á J R, Dixit S M, Thibeault J, et al.
