EMSA of the promoter region for several V. parahaemolyticus genes in the presence (+) or absence (-) of purified LexA protein from this organism. Competition assays (Additional file 3) were conducted to validate the specificity of LexA binding. The absence of purified LexA protein is used as a negative control for each EMSA. The lexA, recA and imuA promoter regions are used as positive controls.
