ID 3.5.2.15 DE Cyanuric acid amidohydrolase. CA Cyanuric acid + H(2)O = biuret + CO(2). CC -!- Along with EC 3.5.1.54 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 -!- A key enzyme in the pathway, catalyzing the ring cleavage of cyanuric CC acid. CC -!- Specific for cyanuric acid as substrate as neither the structurally CC related compounds ammeline (2,4-diamino-6-hydroxy-s-triazine) and CC ammelide (2-amino-4,6-dihydroxy-s-triazine) nor a number of CC pyrimidine compounds, such as uracil and cytosine, can act as CC substrates.
