Compounds I of Catalase and Horse Radish Peroxidase: -Cation Radicals

Compounds I of Catalase and Horse Radish Peroxidase : 7 r - Cation Radicals

Two-electron oxidation of cobaltous actaethylporphyrin [Co(II)(Et).P] yields a stable ...... cation radical [Co(III)(Et)8P]'+·, the optical spectrum of which exhibits spectral changes dependent upon the nature of the counterion. COInparison of these spectra with those of Compounds I of horseradish peroxidase and catalase leads us to propose that these Compounds I contain a 7r-cation radical of ...

Compounds I of catalase and horse radish peroxidase: pi-cation radicals.

Two-electron oxidation of cobaltous octaethylporphyrin [Co(II)(Et)(8)P] yields a stable pi-cation radical [Co(III)(Et)(8)P](2+.), the optical spectrum of which exhibits spectral changes dependent upon the nature of the counterion. Comparison of these spectra with those of Compounds I of horseradish peroxidase and catalase leads us to propose that these Compounds I contain a pi-cation radical of...

Purification of horse-radish peroxidase and comparison of its properties with those of catalase and methaemoglobin.

ABSORPTION OF THE HORSE-RADISH PEROXIDASE IN THE SMALL INTESTINE OF CmCKEN

Holman J.: Absorption of the Horse-radish Peroxidase in the Small Intestine of Chicken. Acta vet. Brno, 47, 1978: 3-6. Localization of the horse-radish peroxidase was studied in the epithelium and stroma of the small intestitlal villi in the chic:, aged 37 days. The enzyme (molecular weight 40.000) was injected into the ligated jejunal loop. Its enteral absorption was shown to proceed via the s...

Is Root Catalase a Bifunctional Catalase-Peroxidase?

Plant catalases exhibit spatial and temporal distribution of their activity. Moreover, except from the typical monofunctional catalase, a bifunctional catalase-peroxidase has been reported. The aim of this study was to investigate whether the leaf and root catalases from six different plant species (Lactuca sativa, Cichorium endivia, Apium graveolens, Petroselinum crispum, Lycopersicon esculent...
