Progresses of Single Molecular Fluorescence Resonance Energy Transfer in Studying Biomacromolecule Dynamic Process / 分析化学

ABSTRACT

Biomacromolecules participate in various kinds of vital processes. Observing and analyzing their structural dynamic and the dynamic processes of intermolecular interaction at molecular level is important for understanding the action mechanism. Since its advent, single molecular fluorescence resonance energy transfer (SM-FRET) has demonstrated its great potential in studying the conformational change and interaction process of biomacromolecules, and a series of new mechanisms have been revealed. This review summarized recent progresses of SM-FRET in studying protein structural dynamic, nucleic acid structural dynamic, protein-protein and protein-nucleic acid interactions.
