This part can be used to characterize BBa_R0011 hybrid promoter using GFP as reporter gene.

The hybrid lac promoter (BBa_R0011), has been designed taking the Plambda promoter (BBa_R0051) and substituting its cI (BBa_C0051) binding sites with two lacI binding sites.

This promoter can be repressed by lacI (BBa_C0012), which can be repressed by lactose or IPTG. Differently from wild type lac promoter, this part does not have any CAP binding sites, so its behaviour is glucose-independent.

Strains bearing a genomic copy of lacI can repress this promoter, which acts as a glucose-independent lactose/IPTG sensor. In the other strains BBa_R0011 acts as a constitutive promoter.
