PlldR_tetR reporter circuit (GFP)

This module works as a reporter for lactate an tetracycline presence. The circuit's key part is the PlldR_tetR promoter (BBa_K2486011), a part inspired by ETH_Zurich 2015 team [http://2015.igem.org/Team:ETH_Zurich/Part_Collection parts collection] of hybrid promoters for LacI and LldR. We adopted tetR operator in our promoter instead of lacI operator because of it's tighter regulation, reducing noise and basal signal of the system. The other components are:

The data of the validation of the parts in the presence of TetR and LldR are described in parts BBa_K2486019 (LldR-based lactate biosensor) and BBa_K2486020 (TetR-based tetracycline biosensor) and here.

Conclusion

The presence of LlldR and lactate affects the circuit as expected, repressing it in the absence of lactate. The presence of TetR and tetracycline could not be adequately mesured probably due to the Tetracycline used, once Anhydrotetracycline was not available.
