Arsenite-transporting ATPase

In enzymology, an arsenite-transporting ATPase is an enzyme that catalyzes the chemical reaction


 * ATP + H2O + arsenitein $$\rightleftharpoons$$ ADP + phosphate + arseniteout

The 3 substrates of this enzyme are ATP, H2O, and arsenite, whereas its 3 products are ADP, phosphate, and arsenite.

This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides acting on acid anhydrides to catalyse transmembrane movement of substances. The systematic name of this enzyme class is ATP phosphohydrolase (arsenite-exporting).

Structural studies
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes, , and.
