General annotation (Comments)

Function

Anion-transporting ATPase. Catalyzes the extrusion of the oxyanions arsenite, antimonite and arsenate. Maintenance of a low intracellular concentration of oxyanion produces resistance to the toxic agents.

Catalytic activity

ATP + H2O + arsenite(In) = ADP + phosphate + arsenite(Out).

Sequence similarities

Belongs to the arsA ATPase family.
