In enzymology, a N-acyl-D-aspartate deacylase (EC 3.5.1.83) is an enzyme that catalyzes the chemical reaction

N-acyl-D-aspartate + H₂O ${\displaystyle \rightleftharpoons }$ a carboxylate + D-aspartate

Thus, the two substrates of this enzyme are N-acyl-D-aspartate and H₂O, whereas its two products are carboxylate and D-aspartate.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is N-acyl-D-aspartate amidohydrolase. It employs one cofactor, zinc.
