The enzyme urate oxidase (UO), uricase or factor-independent urate hydroxylase, absent in humans, catalyzes the oxidation of uric acid to 5-hydroxyisourate:[4]

Uric acid + O2 + H2O → 5-hydroxyisourate + H2O2
5-hydroxyisourate + H2O → 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline
2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline → allantoin + CO2
sequence of oxidation of ureate.
