Experimental Process

EMSA was performed to validate binding of purified LexA upstream of the lexA promoter. DNAse footprint was used to specify site, mutagenesis to precisely define it. RT-PCR was used to confirm expression induced with mitomycin C

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.
