Curation notes

Experimental Process

DNase I footprinting showed that CtrA protected a region in the Cori probe containing a CtrA consensus (TTAA-N7-TTAA). Mutagenesis of the right TTAA motif resulted in the abolishment of binding by CtrA as observed by DNase I footprinting.

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.
