Polypeptides specified by the mercuric resistance (mer) operon of plasmid R100.
Overlapping deletion mutations were constructed in chimaeric plasmids carrying the mer operon of plasmid R100. Polypeptides specified by the mutant plasmids in Escherichia coli minicells correlated with the mer genes as follows: merT, 17- and 16-kDa polypeptides; merP, 9.8- and 9.5-kDa polypeptides; merC, a 14-kDa polypeptide; merA, 65- and 62-kDa polypeptides. The products of the merR and merD genes were not identified. The revised nomenclature of the mer genes is explained.
