Overview
A light control system forms a twp-phases switch can be used to control the production of limonene and linalool by only changing physical conditions. The central part of this light control system is a photosensitive protein --Cph8. When the environment is dark, this protein will be normally activated and binds with OmpR, the formed complex can activate the expression of the downstream genes, produces CS and a thermosensitive inhibitor CI that can block the expression of gene regulated by pλ, which is LS here. CI responses to changes in temperature, specifically it will be deactivated when temperature rises to 42 degrees, thereby LS expresses again. With the presence of red light, Cph8 will be deactivated and expression of CS and CI will terminate.
Generally, the red light in our device will be shut down at night, which means linalool will be synthesized for a nice sleep while limonene will start to be produced with red light in the morning to remove sleepy mind.
Furthermore, we have constructed several light-fluorescent circuits wherein the CS and LS are substituted by superfolder GFP and m1RFP respectively. The peak value and of the two phases and responding time of the switch can be calculated by measuring the fluoresce intensity. In order not to cause the interference between GFP and RFP, they are also placed on two different circuits.
