Amidinoaspartase

In enzymology, an amidinoaspartase (EC 3.5.3.14) is an enzyme that catalyzes the chemical reaction

N-amidino-L-aspartate + H₂O ⇌ L-aspartate + urea

Thus, the two substrates of this enzyme are N-amidino-L-aspartate and H₂O, whereas its two products are L-aspartate and urea.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amidines. The systematic name of this enzyme class is N-amidino-L-aspartate amidinohydrolase. This enzyme is also called amidinoaspartic amidinohydrolase.
