Experimental Process

katG transcription start site was identified by primer extension analysis using mRNA from strain NA1000. katG-lacZ fusion demonstrated OxyR-dependent regulation of katG. EMSA confirmed that this regulation was direct. DNase I footprinting determined OxyR binding region in the katG promoter.

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.
