In enzymology, a formylaspartate deformylase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are N-formyl-L-aspartate and H<sub>2</sub>O, whereas its two products are formate and L-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-formyl-L-aspartate amidohydrolase. This enzyme is also called formylaspartic formylase (formylase I, formylase II). This enzyme participates in histidine metabolism and glyoxylate and dicarboxylate metabolism.
