Artificial multi‐enzyme systems with precise and dynamic control over the enzyme pathway activity are of great significance in bionanotechnology and synthetic biology. Herein, we exploit a spatially addressable DNA nanoplatform for the directional regulation of two enzyme pathways (G6pDH–MDH and G6pDH–LDH) through the control of NAD+ substrate channeling by specifically shifting NAD+ between the two enzyme pairs. We believe that this concept will be useful for the design of regulatory biological circuits for synthetic biology and biomedicine.

通过控制DNA折纸支架上的底物通道的酶途径的方向调节。

对酶途径活性进行精确和动态控制的人工多酶系统在生物纳米技术和合成生物学中具有重要意义。在本文中,我们通过控制NAD +底物通道的移动,通过在两个酶对之间特异性移动NAD +,来利用空间可寻址的DNA纳米平台对两种酶途径(G6pDH–MDH和G6pDH–LDH)的方向进行调控。我们认为,这一概念对于设计用于合成生物学和生物医学的调节性生物回路将是有用的。
