Submitted Parts
We have submitted three T7Lac promoter parts to the registry. The followings show the sequences of these constructs.
BBa_K613007: TAATACGACTCACTATAGGGAGAGGAATTGTGAGCGGATAACAA
Mutant I: TAATGCGACTCACTATAGGACAATTGTGGGCGGACAACAATTCCAA
Mutant II: TAATACGACTCACTACAGGGCGGAATTGTGAGCGGATAACAATTCCAA
Mutant III: CAATCCGACTCACTAAAGAGAGAATTGTGAGCGGATAACAATTCCAA
Predicted strength of the hybrid T7Lac promoters
Expected promoter strength of the mutants (relative to BBa_K613007):Mutant I: <100%
Mutant II: ~100%
Mutant III: ~50%
Expected LacI leaky expression of different mutants:
Mutant I: More than average
Mutant II: Average
Mutant III: Average
Measured strength of the hybrid T7Lac promoters
Using the model we developed in MATLAB, we calculated the following properties with respect to the wild-type promoter.| Promoter | Mutant I | Mutant II | Mutant III |
|---|---|---|---|
| Transcription Strength | 97% | 72% | 127% |
| Translational Efficiency | 6% | 6% | 94% |
| RNA degradation constant (assumed) | 100% | 100% | 100% |
| Protein degradation constant (fit) | 4% | 6% | 60% |
