Experimental Process

vvsA-luxAB reporter fusion showed that vvsA expression repressed by Fur in the presence of iron. Visual inspection of the vvsA promoter identified a Fur box with only two nucleotide differences from the consensus Fur binding site. EMSA showed that Fur bound specifically to the vvsA promoter. DNase I footprinting identified that Fur binding region contained the putative Fur 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.
