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.
