摘要

A fundamental tool of synthetic biology is a type of genetic device that controls the expression of target genes in a trigger-inducible manner, and so can be used to predictably and robustly program cellular behaviour. The number of such gene switches is growing, and switches have been successfully used in combination with other components, such as enzymes to assemble metabolic pathways that produce biofuels and therapeutic drugs, and in designer cells that have the potential to correct metabolic diseases. But the design of circuits of interconnecting switches is often complicated by the fact that each switch is made of natural components and is sensitive to its own predetermined trigger compound. A strategy that produces compatible gene switches tailored to desired trigger compounds would enable the switches to be easily assembled in combination, increasing the precision and complexity with which cellular behaviour can be programmed. Writing in Cell, Green et al describe a method for generating gene switches that can indeed be tailored to desired RNA inputs.
