Catabolite Activator Protein (CAP) Repressed Promoter

We placed the constitutive promoter (BBa_S05450, iGEM) immediately upstream from a catabolite activator protein (CAP) binding site (BBa_M36547, iGEM) in Plasmid E.

For our experiments, we placed this part upstream from GFP in order to assay expression levels through fluorescent intensity. This construct is an adaption of the natural lac operon, which is positively regulated by CAP, since the CAP binding site is naturally upstream of the RNA polymerase binding site. In this construct, we put the CAP binding site downstream in order to repress transcription when CAP binds due to steric hindrance.
