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. (Figure 1).
Modelling results confirmed that built system will work. (Figure2)
A possible track would be to add another regulation system on the adenylate cyclase production with the riboswitch RsmA/rsmY.
