The intermediate free radicals generated from phenols, naphthols and benzoate, in the peroxidase- and oxidase-reactions of horse radish peroxidase and in the peroxidase-reaction of methemoglobin, were studied by electron spin resonance spectroscopy. The difference between the peroxidase- and oxidase-reactions of HRP are demonstrated, i.e., the ferro

In vitro degradation of aflatoxin B1 by horse radish peroxidase
Food Chemistry, 2000Abstract Aflatoxin B 1 (AFB 1 ), extracted from Aspergillus flavus ATCC 15517, was detoxified up to 60% by commercial horse radish peroxidase (HRP) (200 U/mg) in vitro. Partially purified peroxidase enzymes from freshly harvested radish root having 20 and 30 U/mg of protein were made to act upon the toxin in vitro and showed approximately 30 and ...

The oxidation of naphthalene sulfonate dyes by horse radish peroxidase
Archives of Biochemistry and Biophysics, 1982Abstract Horse radish peroxidase catalyses oxidation of ANS and TNS with hydrogen peroxide. TNS peroxidation may be followed fluorimetrically in the presence of as low as 10 −12 m concentrations of the enzyme and permits determination of very low levels of peroxides.

Production of horse radish peroxidase by plant cell culture
Journal of Chemical Technology & Biotechnology, 1987AbstractCalluses were induced from the stem and the root tissues of horse radish plantlets. Cell aggregate selections were carried out on them to obtain a cell line with higher peroxidase activity, and the isozyme patterns of the peroxidases from the cultured cells and their utility values as a clinical diagnostic reagent were investigated.The ...

Inhibition of horse radish peroxidase by specific antisera
Molecular Immunology, 1973Abstract Antiperoxidase has been prepared in the rabbit, cat, mouse, hamster and chicken. All of these antisera inhibit peroxidase activity.

Degratation of 3-hydroxyflavone by horse radish peroxidase
Biochemical and Biophysical Research Communications, 1975Abstract A hydroxylic group in position 3 and a double bond between positions 2 and 3 is the minimum requirement for flavones to be substrates for horse radish peroxidase (EC 1.11.1.7). 3-Hydroxyflavone, fulfilling these requirements, yields on enzymatic cleavage salicylic, phenylglyoxylic and probably benzoic acid.

Oxidation of homogentisic acid catalyzed by horse-radish peroxidase
Biochimica et Biophysica Acta (BBA) - Specialized Section on Enzymological Subjects, 1963Horse-radish peroxidase catalyzes the oxidation of homogentisic acid in the presence of sulfhydryl compounds to form products similar to those obtained by the spontaneous reaction of benzoquinoneacetic acid with sulfhydryl agents. Other heme proteins, such as catalase, cytochrome c, hemoglobin and methemoglobin, do not catalyze this oxidation.

Functional attachment of horse radish peroxidase to plasma-treated surfaces
SPIE Proceedings, 2004Controlling the interaction of surfaces with macromolecules, such as proteins and antibodies, is the key to producing biocompatible prosthetic devices, biosensors and diagnostic arrays. The development of technologies to control these interactions will result in the early detection of disease and have the potential to dramatically reduce costs ...

Changes in catalytic activity of conjugated horse-radish peroxidase
1986To investigate how different sizes of protein ligands change peroxidase catalytic activity, we labeled IgG and chorionic somatommamotropin (HCS) with horse radish peroxidase (HRP) by two-step glutaraldehyde method. Guiacol and o-phenylendiamidine (OPD) were used as hydrogen donors.
