Experimental Process

A consensus search identified the putative binding site. GUS assays of PhoB variable strains grown in phosphate-limited media demonstrated strong expression of the binding site in the PhoB+ strain but not the PhoB- strain.

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.
