Experimental Process

Site in vvhBA promoter identified by DNAse footprinting. Binding further confirmed by site-directed mutagenesis and EMSA. Evidence of regulation with lux fusion assay. Effect on haemolysin production quantified. Evidence of regulation by western of VvhA

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.
