Enzyme Information

3.5.2.17
Hydroxyisourate hydrolase.
based on mapping to UniProt Q4VYA5
5-hydroxyisourate + H(2)O = 5-hydroxy-2-oxo-4-ureido-2,5-dihydro- 1H-imidazole-5-carboxylate.
-!- The reaction is the first stage in the conversion of 5-hydroxyisourate into (S)-allantoin. -!- This reaction will also occur spontaneously, but more slowly.
