Main results
In a first place, biologists and modellers worked on a simple amplification loop.
The modellers proved that a simple amplification loop could not work. There is no state where GFP is not expressed.
Modelling results confirmed that built system will work.
(Figure 3)
As you can see the paraBAD works as expected. We began the construction of the amplification loop (paraBAD_gfp_cyaA).
A possible track would be to add another regulation system on the adenylate cyclase production with the riboswitch RsmA/rsmY.
