ID 3.5.1.54 DE allophanate hydrolase. CA 3 H(+) + H2O + urea-1-carboxylate = 2 CO2 + 2 NH4(+). CC -!- Along with EC 3.5.2.15 and EC 3.5.1.84, forms part of the cyanuric- CC acid metabolism pathway, which degrades s-triazide herbicides, such CC as atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-1,3,5- CC triazine], in bacteria. CC -!- The Saccharomyces cerevisiae enzyme (but not that from green algae) CC also catalyzes the reaction of EC 6.3.4.6, thus bringing about the CC hydrolysis of urea to CO2 and NH3 in the presence of ATP and CC bicarbonate. CC -!- The enzyme from Pseudomonas sp. strain ADP has a narrow substrate CC specificity, being unable to use the structurally analogous compounds CC urea, hydroxyurea or methylcarbamate as substrate.
