In [[enzymology]], a '''nitrate-transporting ATPase''' ({{EC number|3.6.3.26}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:ATP + H<sub>2</sub>O + nitrateout <math>\rightleftharpoons</math> ADP + phosphate + nitratein

The 3 [[substrate (biochemistry)|substrates]] of this enzyme are [[adenosine triphosphate|ATP]], [[water|H<sub>2</sub>O]], and [[nitrate]], whereas its 3 [[product (chemistry)|products]] are [[adenosine diphosphate|ADP]], [[phosphate]], and [[nitrate]].

This enzyme belongs to the family of [[hydrolase]]s, specifically those acting on acid anhydrides to catalyse transmembrane movement of substances. The systematic name of this enzyme class is '''ATP phosphohydrolase (nitrate-importing)'''.
