Regulation of the multiple antibiotic resistance (mar) regulon by marORA sequences in Escherichia coli.

R G Martin1, P S Nyantakyi, J L Rosner.   

Abstract

The mar operon and adjacent sequences were subcloned on a low-copy-number plasmid to identify essential regulatory elements. A 1.1-kbp fragment containing 133 bp of the operator-promoter region (marO), the full marRA gene sequences, and only 10 of 72 marB codons provided a dela mar strain with normal repressibility and inducibility and the ability to beget mar constitutive mutants.
