In order to construct these 3 communities, the key is to solve the problems of communication between different communities. So we use some promoters and proteins of AHL family (Lux, Las, Rhl, Cin signal system). To this end, we have set up the fundament of our project and we want to make it more interesting. Accordingly, we design our system which could satisfy our demanding that when our sensor accepts 2 different changes, our effector could give a different outcome. These different outcome are not limited by the change of quantity of our protein but also the change of kind of our protein. This means, our system could express correct protein according to the environment demanding. To fulfill this task, we have to use at least 5 cell signal communication system. Unfortunately, we just found 4 different cell signal communication systems in the pool of IGEM. So we managed to find a totally new cell signal communication system—the PPy induced-Lux like system.
