General annotation (Comments)

Function	Catalyzes the oxidation of uric acid to 5-hydroxyisourate, which spontaneously decomposes to form allantoin.
Catalytic activity	Urate + O2 + H2O = 5-hydroxyisourate + H2O2.
Enzyme regulation	Repressed by 20-hydroxyecdysone.
Pathway	Purine metabolism; uric acid degradation; (S)-allantoin from uric acid: step 1/3.
Subcellular location	Peroxisome.
Tissue specificity	Malpighian tubules.
Developmental stage	Third instar larvae and adult.
Sequence similarities	Belongs to the uricase family.
