Studies of the chlorinating intermediate of horseradish peroxidase
The chlorinating intermediate of horseradish peroxidase, Compound X, is the only know stable enzymatic halogenating intermediate known. The optical spectrum of Compound X is virtually identical to the optical spectrum of Compound II. Titration of Compound X by a single electron donor, potassium …

Inhibition of horseradish peroxidase activity by specific antibody
… characterize the antibody-mediated inhibition of horseradish peroxidase activity. Inhibition of enzyme activity was determined when alternate substrates were used. Typical biphasic patterns of inhibition were observed with each of five electron donors and three hydroperoxides. In no case was …

Epidemiology of Horseradish Root Discoloration Caused by Verticillium Dahliae
… dahliae revealed that initial infections of horseradish roots occured shortly after planting and probably continued throughout the season. Verticillium dahliae was first isolated from feeder roots one month after planting. Discoloration symptoms were observed two months after planting and …

Engineering a highly enantioselective horseradish peroxidase by directed evolution
… of the commercially useful enzyme, horseradish peroxidase (HRP), toward a chiral phenol. In doing so, we discovered that mutations close to the active site not only preserve HRP catalytic activity but impact its enantioselectivity far greater than distal mutations. We thus examined …

Inhibition and inactivation of prostaglandin synthase-2 and horseradish peroxidase
… acid analogues to the archetypical peroxidase horseradish peroxidase (HRP) revealed the importance of hydrogen bonds to the distal catalytic residues, in particular the distal arginine of HRP. The ability of peroxidases, including PGHS-2, to oxidize a wide variety of compounds makes the design …

Yield and Quality of Pathogen-Free Horseradish (Armoracia Rusticana) Planting Stock
… that TuMV and Verticillium can be removed from horseradish plants by meristem tip culture in vitro. We also developed a sensitive, streamlined PCR-based testing protocol for Verticillium and a reverse transcriptase (RT)-PCR-based technique for TuMV to assess the pathogen status of horseradish …

Somatic Embryogenesis of Pathogen-Free Horseradish (Armoracia Rusticana) Plants in Vitro
"Illinois had been the major producer of horseradish in the United States for many years. Horseradish root production in Illinois had recently decreased due to a disease complex that causes root discoloration and rots. The use of pathogen-free (PF) horseradish planting stock was a means for the …

Identification of fungi and bacteria associated with internally discolored horseradish roots
… associated with the internally discolored horseradish roots. During 2008-2009, 75, 306, 115, and 120, horseradish roots from California, Illinois, Ontario (Canada), and Wisconsin, respectively, were collected and tested for the presence of fungi and bacteria. The roots were …

The Free Radical Nature of Compound I From Horseradish Peroxidase and Chloroperoxidase
Compound Is were prepared from Horseradish Peroxidase (HRP), Chloroperoxidase (CPO), mesohemin substituted Horseradish Peroxidase (M-HRP) and deuterohemin substituted Horseradish Peroxidase. The Compound Is were analyzed by visible absorption, electron paramagnetic resonance (EPR), Mossbauer and …

Evaluation of immobilizing horseradish peroxidase and alcohol oxidase in PVA-AWP polymer
… film thickness on the activity and stability of horseradish peroxidase (HRP) and alcohol oxidase (AOX) when immobilized in a photo-crosslinkable and water-soluble polymer, poly (vinyl alcohol) azide-unit water pendant (PVA-AWP). The immobilized enzyme films were to be used in biosensing …

Developing a System to Produce Uniform Micropropagated Horseradish (Armoracia Rusticana) Plants in Vitro
… and have been presented to the Illinois Horseradish Growers Association (Shehata et al. 2004). Eventually these methods could provide an effective and alternative way for Illinois horseradish growers to produce better quality horseradish roots and regain their market share of the crop. …

Application of additives in horseradish peroxidase-catalyzed removal of phenol derivatives from aqueous solution.
Additives can be used in the horseradish peroxidase (HRP) catalyzed polymerization of phenolic compounds to increase the enzyme turnovers by more than 100-fold. In addition to polyethylene glycol (PEG) and gelatin, some polyelectrolytes may also prove effective as additives. The HRP saving is …

Biochemical and Molecular Approaches to Characterizing the Myrosinase Enzyme System in Horseradish (Armoracia Rusticana)
… cDNA (ArM1) encoding myrosinase was cloned from horseradish root by RACE-PCR. ArM1 has an open reading frame of 1,614 nucleotides with a deduced protein of 538 amino acid and molecular mass of 61.6 kDa. Heterologous expression of ArM1 in Spodoptera frugiperda insect cells resulted in an immune …
