Part:BBa_K2936009
light-controlled repressible system
Usage and Biology
This part contains a light-controlled system and a repression system to achieve the regulations of target gene expression under light conditions. If you want to use this system, you just need to insert the target gene after the Lac operator in the plasmid, which was further transferred into the host cell. We link the repression system of the lactose operon directly behind the original light-controlled system (behind the GFP).In this system, under dark conditions, phosphate group of YF1 protein will be transferred to FixJ protein, and the phosphorylated FixJ protein will initiate the activation of FIXK2 promoter to drive the expression of downstream gene including eGFP and LacI. When the LacI protein was expressed, it will prevent the function of Lac promoter. As a result, the downstream target gene will not be expressed. When induced by light, phosphorylation of FixJ protein was blocked and gene expression regulated by pfixk2 promoter was inhibited. Lac promoter expression was not inhibited, downstream gene will be expressed. Sequence and Features
