Design Notes
This part functions to lower the leakage and raise the level of expression of the downstream gene. As a well-characterized promoter, ptetR has been studied thoroughly with its expression level and leakage. While here we take a unique idea to created a new promoter fusion: we fuse the -35 upstream, -35--10 parts of the stronger pl promoters in lambda phages with the tetO operon regulated by tetracycline. As a promoter fusion of pl and tetO, not only is it regulated by tetR and anhydrotetracycline, but it also inherited the expression level of pl.
