Design Notes

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.
