Degradation of purines: only ureidoglycollate lyase out of four allantoin-degrading enzymes is present in mammals.
It is generally accepted that all of the allantoin-degrading enzymes (allantoinase, allantoicase, ureidoglycollate lyase and urease), used in purine degradation, were lost during mammalian evolution. However, surprisingly, ureidoglycollate lyase has been found in a mammalian tissue. Ureidoglycollate lyase was purified to homogeneity and characterized from rat-liver mitochondria. The apparent Km...
متن کاملIsolation and sequence determination of a cDNA clone for rat peroxisomal urate oxidase: liver-specific expression in the rat.
Urate oxidase (UOxase; urate:oxygen oxidoreductase, EC 1.7.3.3), which catalyzes the oxidation of uric acid to allantoin, is present in most mammals but is absent in humans and certain primates. A cDNA clone for UOxase containing an insert of 1.3 kilobases (kb) was isolated from a lambda gt11 cDNA library prepared from rat liver mRNA. This recombinant clone with a 1283-nucleotide insert has seq...

abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...
15 صفحه اولContamination profile of heavy metals in marine fish and shellfish
Rapid industrialization along with advanced agricultural activities led to the contamination in aquatic environment with heavy metals. Heavy metals ultimately pass into human body through having aquatic animals like fish, prawn and crab. In this study, accumulation of heavy metals (zinc, copper, iron, cadmium and lead) in various organs of four commonly consumed fish (Euthynnus affinis...
متن کاملUrate synthesis in the perfused chick liver.
Urate synthesis was studied in a perfused chicken liver preparation. The perfused liver had an ATP/ADP ratio of 0.29+/-0.05(6) compared with 0.34+/-0.07(10) in liver obtained from chicks under ether anaesthesia. Lactate/pyruvate ratios were 9.4+/-1.7(5) in the perfused liver and 14.8+/-1.8(5) in the rapidly sampled liver. Urate synthesis was only marginally stimulated by glycine, glutamine, asp...
