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.
