FAD-dependent urate hydroxylase (EC 1.14.13.113 HpxO enzyme FAD-dependent urate oxidase urate hydroxylase) is an enzyme with system name urateNADH:oxygen oxidoreductase (5-hydroxyisourate forming).A non-homologous isofunctional enzyme (NISE) to HpxO was found and named HpyO. HpyO was determined to be a typical Michaelian enzyme. These FAD-dependent urate hydroxylases are flavoproteins.
