Experimental Process

EMSA showed that LasR bound specifically to the las-rhl box in the lasI-rsaL intergenic region. DNase I footprinting showed that LasR protected a region that included the 20-bp las-rhl box.

Transcription Factor Binding Sites


Gene Regulation

Regulated genes for each binding site are displayed below. Gene regulation diagrams show binding sites, positively-regulated genes, negatively-regulated genes, both positively and negatively regulated genes, genes with unspecified type of regulation. For each indvidual site, experimental techniques used to determine the site are also given.
