Magnetic labelled horseradish peroxidase–polymer nanoparticles: a recyclable nanobiocatalyst
In this study, the reusability and process stability of nano-reengineered horseradish peroxidase was investigated in a fluorescence-based sensing system for hydrogen peroxide determination as a model application. To this end, dendron macromolecules were attached to the enzyme surface through bio-conjugation techniques. The resulting enzyme–polymer nanoparticles, with an average size of 14(±2) n...
متن کاملHorseradish peroxidase mediated free radical polymerization of methyl methacrylate.
This paper reports the free radical polymerization of methyl methacrylate (MMA) catalyzed by horseradish peroxidase (HRP). A novel method was developed whereby MMA polymerization can be carried out at ambient temperatures in the presence of low concentrations of hydrogen peroxide and 2,4-pentanedione in a mixture of water and a water-miscible solvent. Polymers of MMA formed were highly stereore...
متن کاملIdentification of acetaminophen polymerization products catalyzed by horseradish peroxidase.
Horseradish peroxidase catalyzed the H2O2-dependent oxidation and polymerization of acetaminophen. Six acetaminophen polymers were isolated from horseradish peroxidase reaction mixtures by semipreparative high pressure liquid chromatography. Chemical structures were determined by a combination of electron impact and chemical ionization mass spectrometry and 500-MHz proton magnetic resonance spe...
متن کاملCobalt-substituted horseradish peroxidase.
Horseradish peroxidase can be reconstituted with cobalt porphyrin to give a cobaltic holoenzyme having physicochemical properties quite similar to those of the native ferric protein. The cobaltic protein (Co3+HRP) can be reduced to the cobaltous form (CoHRP), the analogue of ferroperoxidase and the reduced cobalt protein can bind O2 to form an analogue of oxyferroperoxidase (Compound III). Sinc...
متن کاملStudies on Horseradish Peroxidase
The kinetics of the oxidation of p-cresol by Compound II of horseradish peroxidase has been studied by the stopped flow technique at an ionic strength of 0.11 from pH 2 to 11. In acid solution the reaction is kinetically first order in jcresol, but in the alkaline region a saturation effect attributable to complex formation is observed. At very high pH an additional second order reaction betwee...
