The Conformational Dynamics of Cas9 Governing DNA Cleavage Are Revealed by Single-Molecule FRET
Summary: Off-target binding and cleavage by Cas9 pose major challenges in its application.How the conformational dynamics of Cas9 govern its nuclease activity under on- and off-target conditions remains largely unknown.Here, using intra-molecular single-molecule fluorescence resonance energy transfer measurements, we revealed that Cas9 in apo, sgRN
