摘要

DNA 折纸纳米隔室的设计目的是以单向方向捕获折叠酶机器。这种捕获为底物招募和转运到承载蛋白酶的下游区室提供了一个网关机制。动力学和蛋白质组学数据表明，基于 DNA 的模块的物理连接提高了嵌合体的整体性能，并减少了脱靶反应。

Engineering modular enzymes using DNA origami

A DNA origami nanocompartment is designed to trap an unfoldase machine in a unidirectional orientation. This trapping provides a gateway mechanism for substrate recruitment and translocation to a downstream compartment that hosts a protease. Kinetics and proteomics data demonstrate that the physical connection of the DNA-based modules improves the global performance of the chimera and reduces off-target reactions.
