Tools for regulated gene expression in Enterococcus faecalis are extremely limited. In this report, we describe the construction of an expression vector for E. faecalis, designated pCIE, utilizing the PQ pheromone-responsive promoter of plasmid pCF10. We demonstrate that this promoter is tightly repressed, responds to nanogram quantities of the peptide pheromone, and has a large dynamic range. To demonstrate its utility, the promoter was used to control expression of the toxic peptides of two pa  ...[more]
