PiG0109 is a derivate of piG0065 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.

BUFFER Gate Construct
The directional terminator [http://parts.igem.org/Part:BBa_B0015 BBa_B0015] blocks transcription of sfGFP under the strong constitutive promoter [http://parts.igem.org/Part:BBa_J23100 BBa_J23100]. Only if the integrase Bxb1 flips B0015 between the attP and the attB sites, transcription of sfGFP is possible. The pBBR1 origin is present at a copy number of approximately 5, however, the origin is poorly characterized[16]
Signal Propagation Construct
Expression of the integrase Bxb1 and the fluorophore mCherry is induced when LuxR bound to 3OC6-HSL bind to pLuxR. The cis-repressive element (crR12y) inhibits the translation of Bxb1 and mCherry, 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 riboregulator that decreases leakiness of pLuxR. The p15A is present at a copy number of approximately 15 to 25[35].
Combined Sensor and Producer Constructs
Expression of sfGFP and LuxI is induced when LuxR bound to 3OC6-HSL bind to pLuxR. The cis-repressive element (crR12y) inhibits the translation of the succeeding gene, 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 riboregulator that decreases leakiness of pLuxR. The p15A is present at a copy number of approximately 15 to 25[35].
