Promoter activated by LuxR in concert with HSL
This part involves the -10 binding site, the -35 binding site, and the twenty nucleotides between that constitute the lux box. With this part, LuxR functions as a acyl-homoserine lactone-dependent repressor. LuxR resonds to the HSL produced by LuxI, N-(3-oxohexanoyl)-HSL. The Lux box is positioned such that it partially overlaps the consensus -35 and -10 hexamers of an RNA polymerase binding site. A quorum-sensing system involving LuxR, the transcriptional activator, and an acyl-homserine lactone signal regulate the lux operon in vibrio fischeri. In vibrio fischeri, the lux box, which is a 20-base inverted repeat unit, is positioned 42.5 bases upstream of the transcriptional start of the lux operon and is required for transcriptional activation.
design
Quorum-sensing bacteria such as Vibrio fischeri, are able to detected their own population density and implement density-based decision-making，Using the luxI/luxR quorum-sensing system, synthetic biologists have designed a large number of devices in prokaryotic microorganisms.Inevitably, high performance is required from such devices, and this includes reliability, sensitivity, Hence, to improve the properties of population-density switches, we design of ultrasensitive responses use Point mutation
