KEGG   ENZYME: 3.5.2.15
Entry
EC 3.5.2.15                 Enzyme                                 

Name
cyanuric acid amidohydrolase;
atzD (gene name);
trzD (gene name)
Class
Hydrolases;
Acting on carbon-nitrogen bonds, other than peptide bonds;
In cyclic amides
Sysname
cyanuric acid amidohydrolase
Reaction(IUBMB)
cyanuric acid + H2O = 1-carboxybiuret [RN:R12332]
Reaction(KEGG)
R12332
Substrate
cyanuric acid [CPD:C06554];
H2O [CPD:C00001]
Product
1-carboxybiuret [CPD:C22084]
Comment
The enzyme catalyses the ring cleavage of cyanuric acid, an intermediate in the degradation of s-triazide herbicides such as atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-1,3,5-triazine]. The enzyme is highly specific for cyanuric acid. The product was initially thought to be bioret, but was later shown to be 1-carboxybioret.
