Our network is controlled by an engineered promoter, Plac/ara, which features both an activator and a repressor domain. This controls the production of downstream genes to activate other inducible promoters, pBAD and GlnAp2, eventually leading to the production of a repressor protein, lacI, which inhibits Plac/ara, resulting in oscillatory expression. This project shows the feasibility of standardising the biological clock in E. coli and grounds further development for applications in regulated drug/hormone delivery and ion channel control. | Our network is controlled by an engineered promoter, Plac/ara, which features both an activator and a repressor domain.

Therefore, except for Plac/ara we had all the parts ready to be cloned into the iGEM submission vector pSB1C3.
