Characterization of the N-demethylation reactions catalyzed by horseradish peroxidase.
The hydroperoxide-supported N-demethylation reactions catalyzed by horseradish peroxidase have been characterized in detail. The ethyl hydroperoxide-supported N-demethylation of N,N-dimethylaniline by horseradish peroxidase resulted in the formation of equimolar amounts of N-methylaniline and formaldehyde with no other products detectable by high performance liquid chromatography analysis of th...

متن کاملThe reaction of ferrous horseradish peroxidase with hydrogen peroxide.
Hydrogen peroxide reacts with ferrous horseradish peroxidase and converts it to oxyperoxidase in a sequence of two reactions. The first is the reaction of ferrous peroxidase with HzOz to form Compound II; the second is the reaction of Compound II with HzOz to form oxyperoxidase. Both reactions follow second order kinetics, being first order with respect to each of the reactants. They proceed wi...
متن کاملHydrogen Peroxide Biosensors Based on Horseradish Peroxidase and Hemoglobin
Hydrogen peroxide (H2O2) plays a pivotal role in various industrial applications [1]. It is an essential mediator in pharmaceutical, clinical, and environmental research. In addition, it is a byproduct of highly selective oxidases and an important contaminant in several industrial products and wastes [2]. Therefore, a reliable and economical method for the determination of H2O2 is of great sign...
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...
