LuxR binds one site within the qrgB and qrr4 promoters. LuxR binding to the aphA, qrgB, qrr4 and luxC promoters was determined by EMSA with increasing concentrations of LuxR. The first panel is a negative control and shows a DNA fragment containing a region upstream of aphA that does not bind LuxR. Lane 1 in each panel contains no LuxR, and lanes 2–5 contain 10, 50, 100 and 250 nM LuxR respectively.
