lsr promoter of LuxS/AI-2 signaling pathway in E.coli
Quorum sensing is a process of bacterial cell-to-cell communication involving the production and detection of extracellular signaling molecules called autoinducers. And autoinducer-2 (AI-2) has been proposed to serve as a 'universal signal' for interspecies communication. In the LuxS/AI-2 signaling system of E.coli MG1655, AI-2 response involves ATP binding cassette transporter encoded by genes named Lsr (LuxS regulated). Plsr is the promoter of the lsr operon. In our project, we use it to trigger the expression of a reporter gene， GFP.
