Sensor Constructs

piG0058

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].

piG0059

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].

piG0060

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].

piG0062

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].

piG0065

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].

piG0066

Expression of sfGFP is induced when RhlR bound to 4C-HSL bind to pRhlR. The cis-repressive element (crR12) inhibits the translation of sfGFP, since the RBS is blocked by secondary structures of the mRNA. The transcript of the trans-activating element (taR12) 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

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.

piG0110

Expression of sfGFP is induced when RhlR bound to 4C-HSL bind to pRhlR. The cis-repressive element (crR12) inhibits the translation of sfGFP, since the RBS is blocked by secondary structures of the mRNA. The transcript of the trans-activating element (taR12) 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]. 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.
