Curation notes
ClcR and clcABD are borne on the Pseudomonas putida plasmid pAC27, which has no RefSeq equivalent. Bordetella petrii DSM 12804 (NC_010170.1) has a clcR gene (YP_001630141) which has been used as a placeholder.

Experimental Process

DNase I protection of the plasmid-borne clcABD promoter and chromosomal catBC promoter generated a binding footprint for ClcR on each. EMSA confirmed binding to these regions. Qualitative growth analysis and beta-gal assay demonstrated that despite confirmed binding to the catBC promoter, clcR did not activate its 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.
