Allophanate hydrolase

Template:Infobox enzyme In enzymology, an allophanate hydrolase (Template:EC number) is an enzyme that catalyzes the chemical reaction

allophanate + 3 H₂O + H⁺ $\rightleftharpoons$ 2 HCO₃⁻ + 2 NH₄⁺

Thus, the two substrates of this enzyme are allophanate (urea-1-carboxylate or N-carbamoylcarbamate) and H₂O, whereas its two products are HCO₃⁻ and NH₄⁺.

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 urea-1-carboxylate amidohydrolase. This enzyme is also called allophanate lyase. This enzyme participates in urea cycle and metabolism of amino groups and atrazine degradation.
