Since CAP binding is inversely correlated to glucose concentrations (and positively correlated with cyclic AMP (cAMP) levels), this promoter exhibits glucose-inducibility and cAMP-repressibility. We employed this construct as a potential DNA-based glucose biosensor in E coli.

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). When CAP binds to the binding site, expression will be repressed.
