Toggle switch genetic circuit
Webb[23,24]. Genetic switches of this kind have later also been identified as important elements of the Drosophila gap gene network [25]. Note that for these switches the term ‘‘toggle’’ only refers to the capability to be set to either one of two gene expression states, not to the toggle operation, which requires the combinatorial Webb8 mars 2024 · We have developed a toggle switch that uses glucose sensing to enable this two-phase strategy. Temporary glucose starvation precisely and autonomously activates product pathway expression in rich or minimal media, obviating the requirement for expensive inducers. The switch remains stably in the new state even after reintroduction …
