- (S)-ureidoglycolate + H2O glyoxylate + 2 NH3 + CO2
Thus, the two substrates of this enzyme are (S)-ureidoglycolate and H2O, whereas its 3 products are glyoxylate, NH3, and CO2.
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 (S)-ureidoglycolate amidohydrolase (decarboxylating). This enzyme participates in purine metabolism.
Structural studies
editAs of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1XSQ, 1XSR, 1YQC, and 2BDR.
