Light control system with eGFP


Under dark conditions, the phosphate group is transferred from Yf1 protein to FixJ protein, the phosphorylated FixJ protein activates the PfixK2 promoter and then activates the downstream gene expression. When induced by light, the phosphorylation of Fixj protein will be blocked, and the expression of genes regulated by PfixK2 promoters will be inhibited. T--ZJUT-China--part101.png

Characterize

To further verify the effectiveness of the system, the plasmids with the system were transferred into different hosts and cultured for more than 24 hours under blue light and dark light respectively. The fluorescence value of eGFP in the culture medium was measured.

Experimental Results

Detection of expression efficiency of primary light control system in different hosts
