pBAD-dCas9-linker-sfGFP-ssrA

In this part, a fluorescent protein sfGFP is fused to the C-terminal of dCas9 for quantitative characterization. A degradation tag ssrA is added to the end of sfGFP to alleviate the burden caused by dCas9. The expression of this fusion protein is driven by pBAD promoter, which can be triggered by arabinose.This part is an improvement of pBAD dCas9-linker-sfGFP(BBa_K3081002), in which we add a degradation signal peptide ssrA to sfGFP.Then we found that the protein with ssrA was expressed at a lower level than the control protein, with the same concentration of inducer
