In [[enzymology]], a '''polyamine-transporting ATPase''' ({{EC number|3.6.3.31}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]
:ATP + H<sub>2</sub>O + polyamineout <math>\rightleftharpoons</math> ADP + phosphate + polyaminein
The 3 [[substrate (biochemistry)|substrates]] of this enzyme are [[adenosine triphosphate|ATP]], [[water|H<sub>2</sub>O]], and [[polyamine]], whereas its 3 [[product (chemistry)|products]] are [[adenosine diphosphate|ADP]], [[phosphate]], and [[polyamine]].
This enzyme belongs to the family of [[hydrolase]]s, specifically those acting on acid anhydrides to catalyse transmembrane movement of substances. The [[List of enzymes|systematic name]] of this enzyme class is '''ATP phosphohydrolase (polyamine-importing)'''. This enzyme participates in [[abc transporters - general]].
