    Suh, Young JinUniversity of Illinois at Urbana-Champaign2011

    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 …

  7. The Free Radical Nature of Compound I From Horseradish Peroxidase and Chloroperoxidase

    Rutter, Rick J.University of Illinois at Urbana-Champaign2014

    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 …

  9. Application of additives in horseradish peroxidase-catalyzed removal of phenol derivatives from aqueous solution.

    Wu, Yimin.University of Windsor1996

    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 …

  10. Studies on the internalization and intracellular transport of horseradish peroxidase in Chinese hamster ovary cells

    Sullivan, Peter C.Virginia Polytechnic Institute and State University1985

    Soluble horseradish peroxidase (HRP) is internalized by Chinese hamster ovary cells, a cell line of fibroblastic origin (Adams et al., 1982). We have confirmed this result by showing no inhibition of uptake in the presence of divalent cation chelators (EGTA Mg or EDTA), excess (19 mg/ml) yeast …

  12. Studies on the Mechanism of the Chlorination Reactions Catalyzed by Chloroperoxidase and by Horseradish Peroxidase With Chlorite

    Shahangian, ShahramUniversity of Illinois at Urbana-Champaign1982

    Chloroperoxidase catalyzes the dismutation of chlorite-forming chloride, chlorine dioxide, chlorate, and oxygen as products. Chloroperoxidase also catalyzes the decomposition of chlorine dioxide. Chloride, chlorate, and oxygen are the products of the decomposition of chlorine dioxide. The optimum …
