Its expression results in polycistronic mRNA, which codes for a transacetylase and a permease, along with a more well-known enzyme.

Cooperative binding of O-1, O-2, and O-3 allows for its sensitive response to allosteric regulators of its tetrameric inhibitor. In the presence of cAMP, CAP binds upstream of it to recruit RNA polymerase to its promoter. In the lab, that inhibitor is commonly deactivated by IPTG, and its expression is assayed by plating on X-GAL, where beta-galactosidase activity results in blue colonies. FTP, name this functional unit of DNA that allows for the metabolism of a certain disaccharide into glucose and galactose.
