Part:BBa_M36268
LasR-N-(3-oxododecanoyl)-homoserine lactone qsc102 sensor
Quorum sensing is a system bacteria use to coordinate behaviors that correlate to cell density. Each species of bacteria produces and senses a unique, diffusable small molecule. This allows bacteria to "count" how many cells of their species are in the vicinity. Pseudomonas Aeruginosa, an opportunistic human pathogen associated with cystic fibrosis, uses two quorum sensing systems, with one of them being LasI/LasR. LasI produces N-(3-oxododecanoyl)-homoserine lactone, and LasR interacts with this molecule to transcriptionally regulate a variety of quorum sensing genes. One of these genes is qsc102.
This composite part consists of a constitutive promoter (BBa_M36266), a RBS (BBa_M36269), the LasR gene (BBa_M36264), a terminator (BBa_M36135), and the qsc102 promoter (BBa_M36265). This entire construct is optimized for a plasmid that will be transformed into E. coli.
Usage and Biology
This construct will be coupled to a standard fluorescence actuator so that in the presence of N-(3-oxododecanoyl)-homoserine lactone, the part will induce transcription of the fluorescence actuator. Furthermore, this composite part will be used in conjunction with a LasI actuator: BBa_M36263. LasI will produce the N-(3-oxododecanoyl)-homoserine lactone that will be used with the LasR sensor.
