Green light inducible system. In this example of the green light inducible system, CcaS becomes phosphorylated upon illumination at 535 nm as green light activates the system. However, upon red light stimulation the cognate response regulator CcaR is dephosphorylated and the transgene expression is switched off. CcaS Cyanobacteriochrome, CcaR downstream cyanobacteriochrome regulator; pcpcG2 promoter of gene cpcG2 that is regulated by CcaR; cpcB 5′UTR sequence derived from the cpcB gene; ccaR ccaR gene
