Switch Circuit

Detailed Model

binding of tetR to LacI-promotor and LacIIs-promotor

binding of LacI and LacIIs to GFP-promotor

binding of tet to tetR

binding of IPTG to LacI

transcription and translation of LacI

transcription and translation of LacIIs

transcription and translation of tetR

transcription and translation of GFP

dimerization of tetR

dimerization and tetramerization of LacI and LacIIs

Implementation

The model of the switch circuit has been implemented using the Simbiology Toolbox in MATLAB.

For the sake of simplicity, the effects of dimerization and dimerization/tetramerization of tetR and LacI/LacIIs have been neglected. So we did with the additional steps involving the RNApolymerase in the transcription of proteins and the ribosomes in the translation of proteins.
