Fig.6 Location of the LuxR mutant in LuxR
Table.1 Seisitivity of LuxR mutants. Data modified from Collins et.al. Mol. Microbiol. 55, 712–723 (2005)


Collins et.al. described the hyper-sensitive variants of luxR to AHL.(Collins, C. H., Arnold, F. H. & Leadbetter, J. R. Directed evolution of Vibrio fischeri LuxR for increased sensitivity to a broad spectrum of acyl-homoserine lactones. Mol. Microbiol. 55, 712–723 (2005))

私たちはmutated Receiverを用いることで、AHL感受性の違う2種類(WTと変異体)のレシーバーを用意し、delay-timeのバリエーションを増やした。 (小林)
