We combined the 3WJ switch and toehold switch to realize the IMPLY Boolean calculation. When no trigger expressed, this logic gate just likes a 3WJ switch. When trigger A expressed, the trigger will bind to the switch RNA. The binding allows for a branch migration process, exposing AUG and RBS for translation initiation. When trigger B expressed, the trigger will bind to 3WJ switch RNA. The resulting trigger–switch complex has a stable 3WJ structure that effectively sequesters the RBS and start codon within the loop and stem of the switch RNA, respectively, and strongly represses translation. When trigger A and B both expressed, the binding of trigger RNA to the toehold sequence allow the RNA polymerase binds to the former RBS and break open 3WJ stable hairpin.

Design Notes

We combined the 3WJ switch and toehold switch to realize the IMPLY Boolean calculation. When no trigger is expressed, this logic gate just likes a 3WJ switch. When trigger A expressed, the trigger will bind to the switch RNA. The binding allows for a branch migration process, exposing AUG and RBS for translation initiation. When trigger B expressed, the trigger will bind to 3WJ switch RNA. The resulting trigger–switch complex has a stable 3WJ structure that effectively sequesters the RBS and the start codon within the loop and stem of the switch RNA, respectively, and strongly represses translation. When both trigger A and B are expressed, the binding of trigger RNA to the toehold sequence allows the RNA polymerase to bind to the former RBS and break open 3WJ stable hairpin.
