ENTRY       EC 3.5.1.54
NAME        Allophanate hydrolase
CLASS       Hydrolases
            Acting on carbon-nitrogen bonds, other than peptide bonds
            In linear amides
SYSNAME     Urea-1-carboxylate amidohydrolase
REACTION    Urea-1-carboxylate + H2O = 2 CO2 + 2 NH3
SUBSTRATE   Urea-1-carboxylate
            H2O
PRODUCT     CO2
            NH3
COMMENT     The yeast enzyme (but not that from green algae) also catalyses
            the reaction of EC 6.3.4.6, thus bringing about the hydrolysis of
            urea to CO2 and NH3 in the presence of ATP and bicarbonate.
PATHWAY     PATH: MAP00220  Urea cycle and metabolism of amino groups
