Cyanuric acid amidohydrolase

In enzymology, a cyanuric acid amidohydrolase (EC 3.5.2.15) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are cyanuric acid and H₂O, whereas its two products are biuret and CO₂.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amides. The systematic name of this enzyme class is cyanuric acid amidohydrolase. This enzyme participates in atrazine degradation.
