The human urate oxidase (E.C. ) gene, UOX, is assigned to chromosome 1 by Southern analysis of human × hamster cell hybrids. Using fluorescent in . Urate oxidase (Uox), a therapeutic enzyme for treatment of hyperuricemia, is a homotetramer with multiple surface lysines, limiting conventional approaches for albumination. Incorporation of p-azido-l-phenylalanine into two predetermined positions of Uox allowed site-specific linkage of dibenzocyclooctyne-derivatized human serum albumin (HSA.

This study, therefore, aims to express genetically modified human urate oxidase in the methylotrophic yeast Pichia pastoris. Accordingly, the genetically modified human urate oxidase was successfully expressed intracellularly and extracellularly under the control of an alcohol oxidase promoter and was subjected to the enzyme activity assay.
Genetically, the loss of urate oxidase function in humans was caused by two nonsense mutations at codons 33 and and an aberrant splice site. It has been proposed that the loss of urate oxidase gene expression has been advantageous to hominids, since uric acid is a powerful antioxidant and scavenger of singlet oxygen and s: UOX, UOXP, URICASE, Urate oxidase, urate.
In most mammals, the activity of urate oxidase catalyzes the oxidation of uric acid to allantoin; humans and some primates lack this enzyme loss of urate oxidase in the human during primate evolution predisposes man to hyperuricemia, a metabolic disturbance that can lead to gouty arthritis and renal stones (summary by Wu et al., ).

URAT1 (urate transporter 1) Aliases: OAT4L, RST Gene name: Solute carrier family 22 member 12 (SLC22A12) Summary. URAT1, a member of the OAT (organic anion transporter) family, is an anion-exchanging uptake transporter localized to the apical (brush border) membrane of renal proximal tubular cells [1, 2], where it mediates the re-absorption of uric acid from the proximal tubule, thereby.

The normal reference range for urate in human blood is to mg/dL in women and – mg/dL in men. When the level of urate is > mg/dL ( μmol/l), the limit of solubility under physiological conditions, crystals of urate may form as monosodium urate (MSU).
Accordingly, the genetically modified human urate oxidase was successfully expressed intracellularly and extracellularly under the control of an alcohol oxidase promoter and was subjected to the. K e y w o r d s: Urate oxidase (uricase), P. aeruginosa, C. flavigena, partial coding sequence Introduction Urate oxidase or uricase (urate oxygen oxidoreductase, EC ) is an enzyme that catalyzes the oxidation of uric acid to unidentified product then to a more soluble compound, allantoin.

Background. Urate oxidase (EC ) plays an important role in purine degradation pathway and catalyzes uric acid oxidation into allantoin, H 2 O 2 and CO 2 in the presence of oxygen (Collings et al. ).The Aspergillus flavus urate oxidase ( kDa) contains four identical subunits, in which each subunit is associated with one active site.
Urate oxidase is a non-glycosylated enzyme.ting the expression of urate oxidase is limited in verte-brates, except for the activation of rat urate oxidase after treatment with glucagon or carbon tetrachloride (CCl 4) [10,11], and the identiﬁcation of regulatory ele-ments in the urate oxidase promoter of hominoids .
