Trigger RNA(of toehold)

Trigger RNA is a short RNA sequence that can bind to the switch RNA to initiate translation of downstream gene.

In our gene circuit, we need high stability and long half-life of trigger RNA. Based on literature, we found that 5' hairpin could improve stability of mRNA. By imitating this design, we added 5’ hairpin to trigger RNA to meet our need.

In our project we would use trigger RNA to release the expression of mazF when switch-mazF is expressed in excrement. So our engineered bacteria could commit suicide.
