From: Cinnamaldehyde and cinnamaldehyde derivatives reduce virulence in Vibrio spp. by decreasing the DNA-binding activity of the quorum sensing response regulator LuxR

LuxR DNA-binding as determined by mobility shifts and LuxR protein levels as determined by SDS-PAGE. A. Autoradiograph after 5% polacrylamide gel electrophoresis of 32P-labelled LuxR promoter DNA containing the LuxR binding sites, mixed with purified LuxR in the presence (0.19, 0.75 and 1.9 mM) and absence of cinnamaldehyde. B. SDS-PAGE of purified LuxR protein in the presence (0.19, 0.75 and 1.9 mM) or absence of cinnamaldehyde.
