متن کاملThe reaction of xanthine oxidase with molecular oxygen.
The reaction of reduced xanthine oxidase with oxygen occurs in two distinct kinetic phases with the rate of the fast phase being about 10 times greater than that of the slow phase. Comparison of transient state and steady state kinetics demonstrates that only the fast phase of oxidation is catalytically significant. The time course of oxidation is quantitatively independent of the following fac...
متن کاملrole of oxygen-free radicals on the motility of rat ileum effects of xanthine plus xanthine oxidase
the major objective of the present study was to characterize the effects of oxidants generated b xanthine (x) plus xanthine oxidase (xo) on isolated rat ileum motility. the effects of three concentrations of x/xo on the basal tone of the rat ileum preparation were studied for 20 minutes. developed tensions were measured in mg/mg tissues and then expressed as percentage of baseline tension. also...
متن کاملPost-irradiation free radical generation: evidence from the conversion of xanthine dehydrogenase into xanthine oxidase.
The xanthine oxidoreductase (XOR) system which consists of xanthine dehydrogenase (XDH) and xathine oxidase (XO), is one of the major sources of free radicals in biological systems. The XOR system is pre-dominantly present as XDH in normal tissues and converts into the free radical generating XO-form in the damaged tissue. Therefore, the XO-form of the XOR system is expected to be mainly found ...
متن کاملSensitive electrochemical measurement of hydroxyl radical generation induced by the xanthine-xanthine oxidase system.
A sensitive electrochemical measurement system for hydroxyl radical (OH) was developed using enzyme-catalyzed signal amplification. In the presence of 2,6-xylenol as a trapping agent, glucose as a substrate, and pyrroloquinoline quinone-dependent glucose dehydrogenase (PQQ-GDH) as a catalyst, the amperometric signal of the trapping adduct 2,6-dimethylhydroquinone (DMHQ) produced by the hydroxyl...
