Allantoicase

In enzymology, an allantoicase (EC number|3.5.3.4) is an enzyme that catalyzes the chemical reaction

:allantoate + H₂O $ightleftharpoons$ (S)-ureidoglycolate + urea

Thus, the two substrates of this enzyme are allantoate and H₂O, whereas its two products are (S)-ureidoglycolate 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 allantoate amidinohydrolase. This enzyme participates in purine metabolism.

tructural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB link|1O59 and PDB link|1SG3.
