In Vivo & In Vitro Outline
In vitro Main | Why TetR? | Mutant TetRs | MITOMI Data | In-vivo & In-vitro outline
For some of the TetR mutants, we managed to have both an in vitro and in vivo characterization. The results are available in the table below.
| Mutant | Biobrick number | Affinity compared to WT - in vivo | Affinity compared to WT - MITOMI | ATC repression |
|---|---|---|---|---|
| V36F | BBa_K613013 | same | higher | altered |
| V36F W43S | BBa_K613014 | same | not tested | altered |
| E37A W43S T141A | BBa_K613015 | same | altered | altered |
| P39K | BBa_K613016 | no affinity | no affinity | normal |
| Y42F K108E | BBa_K613018 | reduced | not tested | normal |
| P39Q Y42M | BBa_K613019 | no affinity | not tested | normal |
The P39K mutant shows in both cases (in vivo and in vitro) no affinity to the Ptet consensus sequence, showing that our results are consistent between the two characterizations. The V36F mutant either shows a stronger or a similar binding affinity compared to the WT. Finally, the E37A W43S T141A triple mutant either has the same or an altered binding affinity.
The results coming from the in vivo and in vitro part are effectively related, albeit incompletely. We have tested only 3 mutants in both systems ; we would need more characterization results to improve our selection systems, especially the in vivo part.
The MITOMI results can be found here. The in vivo characterizations are on this page.
