In enzymology, an ureidoglycolate hydrolase () is an enzyme that catalyzes the chemical reaction (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 As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes , , , and . References EC 3.5.3 Enzymes of known structure
