Mutant TetRs

We used two distinct strategies to make the mutants:
- Site-specific mutagenesis , which consists of both a plasmid amplification step with forward and reverse primers containing the targeted mutation and a selection step (enzymatic digestion of the methylated dsDNA)
- PCR-induced mutagenesis , which specifically amplifies two halves of the gene of interest from a linear template and introduces a mutation in one of them, followed by a stich-PCR to join the two halves and add the necessary extensions.
The plasmid that we used had a C-terminal eGFP fusion to the TetR, while the linear template had a C-terminal His-tag. The promoters added were SP6 in the first case and T7 in the second.
