近年来,单生物分子探测技术的进步为生物分子的本质提供了重要的信息和更深入的了解。具有重要意义的是单分子荧光共振能量转移(smFRET)在纳米尺度上探测孤立事件和变化的应用。特别是,使用smFRET对解旋酶的研究提供了许多关于这些酶的性质和动力学的信息,并为进一步的研究提供了一个工具箱。在本章中,我们提供了用于解旋酶性质和功能研究的单分子FRET测定的构建和执行的一般指南。
In recent years, advancements in single-biomolecule probing techniques have provided critical information on and greater insight into the nature of biomolecules. Of significance is the application of single-molecule fluorescence resonance energy transfer (smFRET) to probe isolated events and changes at the nanometer scales. In particular, the study of helicases using smFRET has supplied Much information regarding the nature and dynamics of these enzymes and provided a toolbox for further investigations. In this chapter we provide a general guide for the construction and execution of single-molecule FRET assays for the study of helicase properties and functionalities.
