Design Notes

We designed the part to include the synthetic enhancer suite and the NRII helper protein on the same UNS backbone, which allows for the phosphorylation (activation) of the protein product of the synthetic enhancer product (NRI). Making one plasmid reduces the metabolic strain on the cell and further decouples the synthetic enhancer system from LacI/IPTG to allow for minimal inference of our circuits in the complete biological system.

We chose to include UNS overhangs before and after our insert to allow for an ease of clone. UNS sequences are from Torella et. al. Furthermore, the NRII sequence and the synthetic enhancer suite sequences are from Amit et. al.

The enhancer, tet cassette, glnAp2 synthetic promoter, NRI coding region, and mCherry coding region sequences were derived from Amit, R., Garcia, H. G., Phillips, R. & Fraser, S. E. Building enhancers from the ground up: a synthetic biology approach. Cell146, 105–118 (2011). The NRII2302 coding region and the promoter that it is controlled by is derived from the helper plasmid pACT tet from Amit et. al 2011. The UNS sequences at the ends of the insert are derived from Torella, J. P., Boehm, C. R., Lienert, F., Chen, J. H., Way, J. C., & Silver, P. A. (2013).

A huge thanks to all the researchers involved in its original creation!
