利用单分子方法,我们直接观察了HDAC8与各种配体之间的动态相互作用以及催化反应过程中的构象相互转换。统计分析确定了关键的动力学参数,表明酶活性对配体结构和小合成分子的微小变化都高度敏感。
Using single-molecule approaches, we directly observed the dynamic interaction between HDAC8 and various ligands as well as conformational interconversions during the catalytic reaction. Statistical analysis identified key kinetic parameters, demonstrating that the enzymatic activity is highly sensitive to both minor variations in the ligand structures and small synthetic molecules.
