In our experiment, we constructed a plasmid vector with RelE toxin protein connected after the lactose promoter and introduced it into E.coli BL21(DE3). IPTG was used to induce expression and OD600 was detected continuously for 4 hours. Samples were taken every 30 minutes, diluted and plated to determine viable cell counts.

Combination element of RNA thermosensors regulatory RelE toxin protein

RelE is a toxin protein that inhibits translation. RNA thermosensors which could inhibit downstream gene expression when the temperature is 37 ℃ but not affect downstream gene expression significantly when the temperature is below 28 ℃.The combination of two components can regulate the expression of toxin proteins by changing the temperature, and then control the death of engineering bacteria. The circuit is shown in the figure below. 无标题文档 In our experiment, we constructed a plasmid vector with RelE toxin protein connected after the lactose promoter and introduced it into E.coli BL21(DE3).
