The red light-sensing protein Cph8 is expressed in the phosphorylated ground state. It is switched to the unphosphorylated state by 650-nm light and back to the phosphorylated state by 705-nm light. When phosphorylated, Cph8 passes a phosphoryl group to OmpR, which then binds to and activates transcription from PompC. Because it is inactivated by red light, Cph8 can be considered a logical (NOT red) sensor. A genetic inverter or logical NOT gate is used to invert the response of the (NOT red) sensor to that of a red light sensor.
