Former composite part BBa_K3408006 has demonstrated the feasibility of promoter P<sub>nar</sub>, so when our engineered bacteria <i>Bacillus subtilis</i> is in anaerobic environment, promoter P<sub>nar</sub> is activated by global regulator—FNR. Then downstream trigger RNA is expressed. As switch RNA is constantly expressed under the control of promoter P<sub>C1</sub>, the trigger RNA can successfully trigger the Toehold switch, thus leading to the expression of mazF. So <i>Bacillus subtilis</i> can commit suicide. While in aerobic environment, promoter P<sub>nar</sub> ceases to work, Toehold switch cannot be triggered. As a result, mazF can not express.

Pnar-B0034-Trigger RNA-B0015-PCⅠ-Switch RNA-mazF-B0015
We designed this composite part by combining promoter Pnar, trigger RNA, PCⅠ, switch RNA and mazF. So we could utilize it to verify the feasibility of our device, which comprises of Toehold switch and suicide protein—MazF.
Former composite part BBa_K3408006 has demonstrated the feasibility of promoter Pnar, so when our engineered bacteria Bacillus subtilis is in anaerobic environment, promoter Pnar is activated by global regulator—FNR. Then downstream trigger RNA is expressed. As switch RNA is constantly expressed under the control of promoter PC1, the trigger RNA can successfully trigger the Toehold switch, thus leading to the expression of mazF. So Bacillus subtilis can commit suicide. While in aerobic environment, promoter Pnar ceases to work, Toehold switch cannot be triggered. As a result, mazF can not express. This device proves that our suicide module and Toehold switch can successfully combine together.
