Formimidoylaspartate deiminase

In enzymology, a formimidoylaspartate deiminase is an enzyme that catalyzes the chemical reaction


 * N-formimidoyl-L-aspartate + H2O $$\rightleftharpoons$$ N-formyl-L-aspartate + NH3

Thus, the two substrates of this enzyme are N-formimidoyl-L-aspartate and H2O, whereas its two products are N-formyl-L-aspartate and NH3.

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-formimidoyl-L-aspartate iminohydrolase. This enzyme is also called formiminoaspartate deiminase. This enzyme participates in histidine metabolism.
