经典结构生物学只能提供生物大分子的静态快照。单分子Förster共振能量转移(smFRET)为研究生物相关条件下大分子结构的动力学铺平了道路。自1996年首次实施以来,smFRET实验证实了以前假设的机制,并为许多基本的生物过程提供了新的见解,如DNA的维持和修复,转录,翻译和膜运输。我们回顾了22年的贡献,smFRET我们的理解,在生物化学,分子生物学和结构生物学的基本机制。此外,基于目前最先进的smFRET实现,我们强调了smFRET在生物传感,高通量筛选和分子诊断等应用中可能的未来方向。
Classical structural biology can only provide static snapshots of biomacromolecules. Single-molecule Förster resonance energy transfer (smFRET) paved the way for studying dynamics in macromolecular structures under biologically relevant conditions. Since its first implementation in 1996, smFRET experiments have confirmed previously hypothesized mechanisms and provided new insights into many fundamental biological processes, such as DNA maintenance and repair, transcription, translation, and membrane transport. We review 22 years of contributions of smFRET to our understanding of basic mechanisms in biochemistry, molecular biology, and structural biology. Additionally, building on current state-of-the-art implementations of smFRET, we highlight possible future directions for smFRET in applications such as biosensing, high-throughput screening, and molecular diagnostics.
