Thermal stabilization of glucose oxidase and glucoamylase by physical entrapment.
Physical entrapment was used as an approach to achieve thermal stabilization of enzymes. The t 1/2 values for the thermoinactivation of glucose oxidase and glucoamylase were increased several-fold by their entrapment in polyacrylamide gels. In polyacrylate gels the individual enzymes behaved differently, probably owing to microenvironmental effects arising by the polyelectrolyte nature of the c...
متن کاملModification of galactose oxidase to introduce glucose 6-oxidase activity.
The selective oxidation of the 6-hydroxy group of D-glucose to introduce an aldehyde functionality is not catalyzed by known oxidase enzymes. Selective functionalization at the glucose C-6 position in oligoand polysaccharides is a synthetically useful reaction that would greatly facilitate further chemical modifications for food, pharmaceutical, and materials applications. We chose the fungal e...
متن کاملGlucose Oxidase Catalyzed Self-Assembly of Bioelectroactive Gold Nanostructures
Glucose oxidase catalyzes the formation of metallic gold particles in immediate proximity of the protein from gold (III) chloride in the absence of any other catalytic or reductive substrates. The protein-mediated gold reduction reaction leads to size-controllable gold particle formation and concomitant association of the enzyme in an electrically conductive metallic template. Such an enzyme im...
متن کاملOnion, a Potent Inhibitor of Xantine Oxidase
Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...
