Experimental Process

RNase protection assays and visual sequence inspection of the sodB promoter determined a single nucleotide polymorphism at the -5 bp affects the regulation of sodB by apo-Fur in H.pylori G27, H.pylori 26695, H.pylori J99, and H.pylori HPAG1. EMSAs confirmed that apo-Fur binds specifically to the sodB promoters in H.pylori G27 and H.pylori 26695.

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.
