Curation notes
they report motif similar to cyano LexA, but not support it experimentally. This has been later revised PMID: 18555801

Experimental Process

Site identified through promoter deletion series coupled to EMSA. Differential expression of lexA and crhR shown by Northern blot. Verification of repression by in-vitro transcription.

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.
