Part:BBa_K2936009
light-controlled repressible system
This part contains a light-controlled system and a repression system to achieve downstream gene expression under light conditions rather than working in dark conditions. In this system, under dark conditions, phosphorylated FixJ protein was transferred from YF1 protein to FixJ protein, and phosphorylated FixJ protein activated pFIXK2 promoter, then activated lacI protein expression. When the LacI protein binds to LacO, it prevents the downward expression of Lac promoter, the target gene is not activated. When cultured under light conditions, phosphorylation of FixJ protein was blocked and gene expression regulated by pfixk2 promoter was inhibited. Lac promoter expression was not inhibited, target gene expression was normal. If you want to use this system,you just need to link the target gene to the lactose operon gene and then introducing plasmid into the host cell.After that,If the transformant is successfully selected, it is possible to express the target gene by illumination.
