Enzyme Information

1.7.3.3
Factor independent urate hydroxylase.
based on mapping to UniProt D0VWQ1
Urate + O(2) + H(2)O = 5-hydroxyisourate + H(2)O(2).
-!- Was previously thought to be a copper protein, but it is now known that the enzymes from soybean (Glycine max), the mold Aspergillus flavus and Bacillus subtilis contains no copper nor any other transition-metal ion. -!- The 5-hydroxyisourate formed decomposes spontaneously to form allantoin and CO(2), although there is an enzyme-catalyzed pathway in which EC 3.5.2.17 catalyzes the first step. -!- The enzyme is different from EC 1.14.13.113.
