AND GATE-input_AHL+red light
The circuit to receive input signals is composed of AND GATE, quorum sensing promoter and light-controlled promoter. After being induced by AHL, pLuxR promoter activates the expression of T7 RNA polymerase (T7 ptag) which contains two amber mutations. The expression of a special tRNA (supD), which is used to identify amber mutation, is activated by Pλ promoter without the restraint of CI protein. In the wild-type E.coli, amber mutation will inhibit the translation of T7 RNA polymerase, and red light could inhibit the produce of CI protein(for more information, see the part"PompC-NOT Gate"). Therefore, when AHL and red light exist together, T7 RNA polymerase will be expressed, and then T7 promoter will be activated to express the downstream gene.
