AHL sfGFP+ASV reporter

This composite part produces sfGFP when a large enough concentration of lactone (AHL) is present in the medium. In this case, it constitutively produces LuxR, which binds to the lactone present in the medium and together, they form a complex that activates the pLux promoter, generating the sfGFP whose fluorescence can be measured. The schematics of this composite part can be seen in Figure 1.

This system allows a fast report on the AHL concentrations in the medium, something important to know the amount of protein. The composite part is Biobrick compatible.

This composite part is composed by all the following parts:

BBa_B0015: A reliable double terminator that consists on BBa_B0010 and BBa_B0012.

BBa_B0033: A weak RBS. The RBS.4 (derivative of BBa_0030).

BBa_B0032: A medium RBS. The RBS.3 (medium) (derivative of BBa_0030

BBa_R0062: LuxR & HSL regulated promoter.

BBa_J72005: Ptet Promoter. Is activated by the AHL-LuxR complex
