It is activated usingIPTG.
This structure encodes a tetrameric protein that binds to O1, O2, and O3 sites. One part of thissystem is joined to the UAS sequence in a common two-hybrid assay reporter. It is activated usingIPTG. It is positively regulated by the Catabolite Activator Protein, which binds to cAMP. Itsmutations include one which stops the binding of a repressor protein, leading to constitutiveactivation, and a super-repressor mutation in which the repressor fails to disassociate. It encodes a(*) transacetylase, permease, and galactosidase as part of a polycistronic RNA. It is minimally activatedwhen glucose is high. It was first characterized by Jacob and Monod in E. Coli.
