我们开发了一种混合合成电路,它可以选择天然细菌群体感应自诱导剂-2的遗传调控,并施加一个额外的外部控制器来维持严格控制的基因表达。这种双输入遗传控制器经过数学建模,根据设计,可以在三种模式下运行:本构模式,可实现一致和高水平的表达;一种严格压抑的模式,其中几乎没有背景表达;以及诱导模式,其中两种信号(阿拉伯糖和自诱导剂-2)的浓度决定感兴趣基因的净扩增。我们展示了该电路在工程益生菌大肠杆菌中控制人粒细胞巨噬细胞集落刺激因子表达的实用性。这种双输入遗传控制器是第一个同源 AI-2 群体感应电路,能够在三种不同模式下运行。我们相信,由于其多功能特性,它具有广泛的生物技术应用潜力。
We developed a hybrid synthetic circuit that co-opts the genetic regulation of the native bacterial quorum sensing autoinducer-2 and imposes an extra external controller for maintaining tightly controlled gene expression. This dual-input genetic controller was mathematically modeled and, by design, can be operated in three modes: a constitutive mode that enables consistent and high levels of expression; a tightly repressed mode in which there is very little background expression; and an inducible mode in which concentrations of two signals (arabinose and autoinducer-2) determine the net amplification of the gene(s)-of-interest. We demonstrate the utility of the circuit for the controlled expression of human granulocyte macrophage colony stimulating factor in an engineered probiotic E. coli. This dual-input genetic controller is the first homologous AI-2 quorum sensing circuit that has the ability to be operated in three different modes. We believe it has the potential for wide-ranging biotechnological applications due its versatile features.
