Biuret amidohydrolase

In enzymology, a biuret amidohydrolase (EC 3.5.1.84) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are biuret and H₂O, whereas its 3 products are urea, CO₂, and NH₃.

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