>TIGR00345 arsA arsenite-activated ATPase (arsA); InterPro: IPR003348 This ATPase is involved in the removal of arsenate, antimonite, and arsenate from the cell. In Escherichia coli an anion-translocating ATPase has been identified as the product of the arsenical resistance operon of resistance plasmid R773. This ATP-driven oxyanion pump catalyses extrusion of the oxyanions arsenite, antimonite and arsenate. Maintenance of a low intracellular concentration of oxyanion produces resistance to the toxic agents. The pump is composed of two polypeptides, the products of the arsA and arsB genes. This two-subunit enzyme produces resistance to arsenite and antimonite. A third gene, arsC, expands the substrate specificity to allow for arsenate pumping and resistance . The ArsA and ArsB proteins form a membrane-bound pump that functions as an oxyanion-translocating ATPase. The ArsC protein is an arsenate reductase that reduces arsenate to arsenite, which is subsequently pumped out of the cell .; GO: 0005524 ATP binding, 0006820 anion transport, 0016020 membrane.
