First lure sequence upstream of eGFP

This part is an off-target detecting platform for dCas9-ω. We put this part in the plasmid and transform it into △rpoZ-MG1655, a strain of E.coli that is koncked out rpoZ. If dCas9-ω is binding to the lure sequence, the subnit Omega fused to dCas9 C-terminal can activate the expression of reporter by recruiting the RNAP holoenzyme and the cell would emit green fluorescence,which means dCas9-ωis off-target, else the weak promoter and the lack of rpoZ makes the reporter cannot express or just have a quite low expression level.

According to the refrence, the off-target rate of the lure sequence in this part is 0.08286%.
