Sensor Constructs
Expression of sfGFP is induced when LasR bound to 3OC12-HSL bind to pLasR. The p15A is present at a copy number of approximately 15 to 25[35].
Expression of sfGFP is induced when LuxR bound to 3OC6-HSL bind to pLuxR. The p15A is present at a copy number of approximately 15 to 25[35].
Expression of sfGFP is induced when RhlR bound to 4C-HSL bind to pRhlR. The p15A is present at a copy number of approximately 15 to 25[35].
Expression of sfGFP is induced when LuxR bound to 3OC6-HSL bind to pLuxR. The cis-repressive element (crR12y) inhibits the translation of sfGFP, since the RBS is blocked by secondary structures of the mRNA. The p15A is present at a copy number of approximately 15 to 25[35].
Expression of sfGFP is induced when LuxR bound to 3OC6-HSL bind to pLuxR. 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 riboregulator that decreases leakiness of pLuxR. The p15A is present at a copy number of approximately 15 to 25[35].

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 BBa_B0015 blocks transcription of sfGFP under the strong constitutive promoter 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.

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].
