Design Notes

We were cautious to scramble only those bases involved in TetR binding, while keeping other bases the same in order to maintain as best we can the spacing and structure of the original promoter. The resulting promoter is one base shorter than the original as a cytosine was lost during assembly. However, we accepted this mutation because it was located in the second scrambled binding region and the promoter functioned as expected when inserted in repClone (see J100312).

The original sequence is the TetR repressible promoter, R0040. Binding regions were identified from Orth P, et al., "Structural basis of gene regulation by the tetracycline inducible Tet repressor-operator system." DOI: 10.1038/73324
