pSB1C3-tra-lysis

This composite part confers the ability for engineered bacteria to undergo self-destruction when perceiving the high cell density. When we add IPTG, traI protein will be expressed and take charge of the formation of ligand, then traR, will bind to the ligand and become active and combine to Ptra, increasing the expression of downstream lysis E.
