LuxR-I-Plux-GFP-1


This composite part is based on the Lux quorum-sensing system from Vibrio fischerii. It consists of a Lux receiver device and a GFP reporter that is activated in the presence of a 3O-C6 AHL signal.

Quorum sensing is a naturally occurring mechanism that certain strains of bacteria use to regulate gene expression in response to their population density. These bacteria secrete autoinducer signalling molecules, such as N-acyl homoserine lactones (AHLs), that bind to transcription factors to alter gene expression. In this case, the constitutively expressed LuxR transcriptional regulator (part1: https://parts.igem.org/Part:BBa_K2267029 ) is activated by the binding of 3O-C6 AHL, an AHL quorum signal. The activated LuxR regulator binds to a LuxR-inducible promoter, pLux, upstream of a GFP reporter. As a result, GFP is expressed when the receiver device is induced with 3O-C6 AHL. We designed this part to characterize the activation range of the Lux receiver device.
