This project involves the joining of two proteins Jun and Fos each fused to a half terminus of YFP.
Subsequently, both of these chimeric proteins were fused to a beta gene that codes for a membrane protein. The
N- and C-terminus of YFP were obtained by PCR, then ligated into 2 vectors, containing Jun-beta and the Fos-beta respectively.
Two cell populations - one expressing Jun-beta-YFPN and the other, Fos-beta-YFPC - were combined and the two proteins were expressed, ideally resulting in the fusion of the Jun and Fos proteins on the cell membrane. This would result in the binding of the two halves of the YFP protein resulting in fluorescence.

The Elowitz Repressilator attempts to decrease the loss of standard oscillations that previous repressilators faced by utilizing quorum sensing as a means of synchronizing and maintaining standard oscillations. We expanded on this theory by adding YFP and CFP to allow a visual confirmation of the oscillation, and a TetR promoter in front of the LuxR gene and cI after the LuxI gene. Our hopes were that this would assist in standardizing the oscillation of the bacteria.
