Expression of sfGFP is induced when RhlR bound to 4C-HSL bind to pRhlR. The cis-repressive element (crR12y) inhibits the translation of sfGFP, since the RBS is blocked by secondary structures of the mRNA. The transcript of the trans-activating element (taR12y) binds to the transcript of the cis-repressive element, hence the RBS is not blocked anymore. The two elements build a [http://2014.igem.org/Team:ETH_Zurich/expresults#Riboregulators riboregulator] that decreases leakiness of pLuxR. The p15A is present at a copy number of approximately 15 to 25<sup>[[Team:ETH_Zurich/project/references#refChang|[35]]]</sup>.

PiG0110 is a derivate of piG0066 where the restriction sites EcoRI and XbaI have been removed. Thus, the two constructs slightly differ in the sequence of the 3'-end of the trans-activating element and in the sequence of the 5'-end of the cis-repressive element.
