Abstract
- The mechanism by which CatR activates the catBC operon which encodes enzymes involved in benzoate degradation in Pseudomonas putida was examined. Gel shift studies demonstrated that the inducer, cis,cis-muconate, increases the binding affinity of CatR for the catBCpromoter region. In addition, cic,cis-muconate allows CatR to bind to a second site of the catBC promoter region, thereby activating catBC transcription. However, binding of CatR to this activation binding site required an intact repression binding site.
