Separate resistances to arsenate and arsenite (antimonate) encoded by the arsenical resistance operon of R factor R773.

Abstract

The arsenical resistance operon of R factor R773 was analyzed by subcloning and insertional inactivation. The operon was found to have two functional regions, the promoter-proximal region encoding resistance to arsenite and antimonate and the promoter-distal region encoding arsenate resistance. A unique 1.6-kilobase fragment was shown to be sufficient to encode arsenate resistance and produce arsenate extrusion from intact cells.
