In enzymology a polar-amino-acid-transporting ATPase (EC 3.6.3.21) is an enzyme that catalyzes the chemical reactionATP + H2O + polar amino acidout ADP + phosphate + polar amino acidinThe 3 substrates of this enzyme are ATP H2O and polar amino acid whereas its 3 products are ADP phosphate and polar amino acid.This enzyme belongs to the family of hydrolases specifically those acting on acid anhydrides to catalyse transmembrane movement of substances.
