OmpR fused the N-terminus of split EPIC luciferase

Fusion protein consisting of the N-terminus of split EPIC luciferase fused via a mixed linker to OmpR under the control of a medium anderson promoter (BBa_J23118) and a weak RBS (BBa_B0032).

The results shown in Figure 1 indicate that some of the OmpR-NLuc linkers allowed the fused OmpR to retain a significant amount of upregulation capability, specifically FFF, RFFF, and RFFR linkers. However, for these constructs the high expression of GFP in uninduced conditions highlights the leakiness of the pOmpC promoter that has been reported by previous iGEM teams (BBa_R0082). In line with expectations, for most constructs GFP fluorescence increased upon sucrose induction, albeit in a very low amount (34% in the best case for RFFR linker).
