Effector device in timed suicide switch

2022 SZU-China plans to design a timed suicide switch mediated by a classical synthetic gene oscillator. The core of the effector is the MazEF toxin-antitoxin system, in which the antitoxin mazE is controlled by the Promoter tetR , and the antitoxin mazF is controlled by the constitutive promoter PJ23110. The MazEF system is an important component of the subtilisin-antitoxin system, which leads to programmed cell death. MazF is an mRNA endonuclease that specifically cleaves a five-base UACAU sequence on RNA. In the presence of MazE, MazF has a higher affinity for MazE than its RNA substrate. MazE binds to MazF to occupy its active site, rendering it unable to bind or cleave the mRNA.

-SZU-China plans to design an auto-timing kill switch mediated by a classical oscillator. The core of the effector is the mazEF toxin system, in which the toxic protein mazE is controlled by the PtetR promoter, and the antitoxin mazF is controlled by the constitutive promoter PJ23110. The mazEF system is an important component of the subtilisin-antitoxin system, which leads to programmed cell death. MazF is an mRNA endonuclease that specifically cleaves a five-base UACAU sequence on RNA. In the presence of MazE, MazF has a higher affinity for MazE than its RNA substrate. MazE binds to MazF to occupy its active site, rendering it unable to bind or cleave the substrate RNA.
