uricase

 [u´rĭ-kās]
an enzyme that catalyzes the conversion of uric acid to allantoin.

u·rate ox·i·dase

[MIM*191540]
a copper-containing, oxygen-requiring oxidoreductase that oxidizes uric acid; used in the clinical diagnosis of increased uric acid levels.
Synonym(s): uricase

uricase

(u'ri-kas?, -kaz?) [ uric + -ase]
An enzyme present in the liver and kidneys of most mammals, but not humans. This enzyme is capable of oxidizing uric acid into allantoin and carbon dioxide. Synonym: urate oxidase

According to Selecta, this reduced rate of gout flares appears to be substantially lower than the incidence of gout flares reported in clinical trials involving the current FDA-approved uricase.
This research applied both adsorption on zeolite and entrapment by [kappa]-carrageenan on the immobilisation of L.plantarum Mar8 producing uricase. Optimisation experiment and characterisation of both kinetics and stability were carried out to develop a more rapid and simpler uric acid biosensor.
These drugs include uricases and selective uric acid reabsorption inhibitors.
To evaluate the mechanism whereby hyperuricemia impairs kidney function, we orally administered oxonic acid (OA), the uricase inhibitor, to male Sprague-Dawley rats [18].

Despite these promising data, we noticed that the plasma uric acid (UA) levels in most studies were normal or even low because of the degradation of uricase, an enzyme that converts uric acid to allantoin, which is much more soluble than uric acid [10].

In this procedure uric acid is oxidized with the uricase, and in the presence of the generated hydrogen peroxide, a phenolic compound and 4-aminoantipyrine forms a red-colored quinoneimine and the absorbance of the quinoneimine chromagen, measured by spectrophotometry, is directly associated with the amount of uric acid in the sample (Thomas 1998).
Uric acid was originally measured in serum at visit 2 (1990-92) at the University of Minnesota using the Coulter DACOS system using an uricase measurement procedure (interassay CV = 2.7%) (12).
It was revealed that uricase inhibi-tor produce hyperuricemia, that initiated hypertension and reduced nitric oxide generation in the macula den-sa.
