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.

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 CL 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 CL protein(for more information, see the part"PompC-NOT Gate").
