Usage and Biology

We found this well-characterized promoter pLasRV from P. aeruginosa cloned by Paul Freemont group in Imperial College, with in vivo and in vitro expression data thoroughly presented in the research articles [1]. Notably, researchers developed a cell-free biosensor based on this promoter to detect the concentration of OdDHL in sputum samples [2]. More attempts to work on this inducible promoter in iGEM will deepen the understanding of quorum sensing in P. aeruginosa and facilitate the exploitation of biomarker-based biosensors.
