Experimental Process

LuxT was identified as binding the smcR promoter through SDS-PAGE. EMSAs confirmed that it binds specifically and DNAse footprint identified a protected region with sequence AGTGCAATACGCTATTTACTATCACA. A luxT- mutant was shown to induce smcR expression through Western blot and luciferase reporter.

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.
