Design Notes

we use cytokinin-mediated quorum sensing circuits from Arabidopsis thaliana makes our engineered microorganisms only reaches a certain population density will start fermentation process, used for decoupling competition between cell growth and fermentation. Cytokinin isopentenyladenine (IP), as quorum sensing molecule, is the product of ATP catalyzed by AtlPT4. This Quorum-sensing systems were used to test the effect of IP concentration on the expression of target genes, and thus AtlPT4 was not available. When the signal molecule IP reaches a certain concentration, it activates the SSRE promoter and initiates transcription.
