Design Notes

First methionine codon was shifted to fit a FLAG-tag in the reading frame. Stop codon was also removed to guarantee translation of reporter gene afterwards. It’s important to note that the toxin-antitoxin system MazE/F is already present and constantly expressed in the strain we use, therefore a baseline expression of the native system is given. The endogenous MazE/F system regulates its own gene expression[1]. We therefore decided to use a different promoter than the native one to prevent interference by the toxin-antitoxin complex.
