1.7.3.3 urate + O2 + H2O Aspergillus flavus urate oxidase catalyzes the hydroxylation of uric acid into the metastable product 5-hydroxyisourate in the presence of molecular oxygen as part of the purine degradation pathway. 5-Hydroxyisourate decays slowly to allantoin, a process independent of oxygen and associated with the release of CO 5-hydroxyisourate + H2O2

1.7.3.3 urate + O2 + H2O substrate binding involves residues Arg176 and Glu228, that hold the substrate, Phe159 closing one end of the cavity below, and the two residues Asn254 and Thr57, forming another tweezers above the mean plane of the ligand that construct a location where efficient electron transfer can take place at a low energy level via the catalytic triad Thr57, Lys10, and His256 Aspergillus flavus 5-hydroxyisourate + H2O2
