单分子酶学研究进展

Research Progresses in Single Molecule Enzymology

源于20世纪90年代的单分子显微成像技术成功实现了对单分子酶的催化过程实时监控,此后单分子酶学的研究进入了快速的发展时期,发现了多种酶的新单分子行为及反应机制。单分子酶学的研究能够发现隐藏于整体平均水平下的单个酶分子的个体行为,揭示了酶与底物作用的动态变化,加深了人们对各种生化反应的理解。

The single molecule imaging and technologies that developed in 1990 s have successfully probed the dynamics of single molecule enzyme catalysis in real time in vitro. Ever since then, single molecule enzymology has entered the golden age of rapid developing. Individual features of each enzyme hidden in the overall average have been discovered,and many new catalytic mechanisms have been proposed. Single molecule enzymology sheds light on the dynamic interactions between enzymes and substrates or products,deepening the understanding of biochemical reactions. This review described the recent research progresses of single molecule protease and ribozyme.
