通过将核糖开关与细胞可穿透的光笼小分子配体相结合,构建了一个光化学基因控制元件,从而能够在空间和时间上控制细菌细胞中的基因表达。由于这一策略的简单性,再加上能够在各种微生物、植物和真菌中产生具有量身定制的配体特异性和输出的合成核糖开关,这种方法可能提供一种在体内光控制基因表达的一般策略。利用光激活核糖开关的能力使人们能够高精度地询问和操纵广泛的生物过程,并将在人工遗传电路的调节方面具有广泛的用途。
By combining a riboswitch with a cell-permeable photocaged small molecule ligand, an optochemical gene control element was constructed, enabling spatial and temporal control of gene expression in bacterial cells. Because of the simplicity of this strategy, coupled with the ability to create synthetic riboswitches with tailored ligand specificities and output in a variety of microorganisms, plants, and fungi, this approach may afford a general strategy to photo-control gene expression in vivo. The ability to activate riboswitches using light enables the interrogation and manipulation of a wide range of biological processes with high precision, and will have broad utility in regulation of artificial genetic circuits.
