TetR promoted with LuxI downstream. LuxI is an enzyme that produces AHL and will produce the red fluorescent protein (RFP). The AHL produced is exported from the cell where it then forms a complex with the LuxR protein that is produced by the AHL sensor within the Receiver cell.

The AHL sensor is TetR promoted and forms the Lux R protien which then forms a complex with AHL. This LuxR and AHL complex then activates the pLUXR promoter. Downstream of the pLUXR promoter is the LACI protein. LacI inhibit the pLAC promoter on the "Freeze Machine".

A promoter that is regulated by LacI will promote the production of LasI, MotB, and cI. This will subsequently inhibit the production of CFP and LasR. In the presence of LacI, however, MotB, LasI, and cI will not be produced. CFP will therefore be produced along with LasR and LacI. This results in the "freezing" of the cell.

Brown 2006 iGEM entry

As the race to the finish draws near for iGEM 2006, our team has compiled a detailed summary of our summers work. This includes our initial ideas, designs, models and the parts that we have added to the registry. We began the summer with grand plans to design a game of bacterial freeze tag, modeled after the popular children's game where one player tries to catch the other. Our efforts were then switched to the extension of the bi-stable toggle switch and the design of a tri-stable toggle switch. Our projects highlight the team's creative and innovative approaches to designing and engineering working biological systems.
