Descrição geral

Chloroperoxidase is a heme containing glycoprotein that is secreted from fungus. Chloroperoxidase (CPO) is a extracellular heme glycoenzyme containing ferriprotoporphyrin IX as the prosthetic group.[1]

Aplicação

A useful alternative to lactoperoxidase for 131I ion labeling studies, for bromination of proteins, and for 36Cl labeling of macromolecules in long-term isolation procedures.
Chloroperoxidase from Caldariomyces fumagois is useful alternative to lactoperoxidase for 131I ion labeling studies, for bromination of proteins, and for 36Cl labeling of macromolecules in long-term isolation procedures. It has been used to study biocatalytic oxidation in polymersome nanoreactors [2].
It has been used to study biocatalytic oxidation in polymersome nanoreactors.[2]

Ações bioquímicas/fisiológicas

Chloroperoxidase (CPO) is secreted from fungus and exhibits a broad spectrum of chemical reactivities. It is a peroxide-dependent chlorinating enzyme and it also catalyzes peroxidase, catalase and cytochrome P450-type reactions of dehydrogenation, hydrogenperoxide (H2O2) decomposition and oxygen insertion, respectively. The enzyme has magnetic and spectroscopic properties similar to that of cyctochrome P-450. CPO from the fungus Caldariomyces fumago has the capacity to chlorinate aromatic hydrocarbons, including polycyclic aromatic hydrocarbons (PAHs). PAHs are considered to be a potential health risk because of their possible carcinogenic and mutagenic activities and are widely dispersed in the environment.[3]

Definição da unidade

One unit will catalyze the conversion of 1.0 μmole of monochlorodimedon to dichlorodimedon per min at pH 2.75 at 25 °C in the presence of potassium chloride and H2O2.

Near-ultraviolet resonance Raman spectra of chloroperoxidase derivatives and high valent intermediates show frequencies that can be systematically assigned. In accord with previous observations of low v4 frequencies for the ferric enzyme, and quite low v4 frequencies for the ferrous enzyme

Chloroperoxidase from Caldariomyces fumago was able to chlorinate 17 of 20 aromatic hydrocarbons assayed in the presence of hydrogen peroxide and chloride ions. Reaction rates varied from 0.6 min(-1) for naphthalene to 758 min(-1) for 9-methylanthracene. Mono-, di- and tri-chlorinated

Heme peroxidases are subject to a mechanism-based oxidative inactivation. During the catalytic cycle, the heme group is activated to form highly oxidizing species, which may extract electrons from the protein itself. In this work, we analyze changes in residues prone

Azide is a well-known inhibitor of heme-enzymes. Herein, we report the counter-intuitive observation that at some concentration regimes, incorporation of azide in the reaction medium enhances chloroperoxidase (CPO, a heme-enzyme) mediated one-electron abstractions from several substrates. A diffusible azidyl radical

We report that incorporation of very low concentrations of redox protein cytochrome c and redox active small molecule vitamin C impacted the outcome of one-electron oxidations mediated by structurally distinct plant/fungal heme peroxidases. Evidence suggests that cytochrome c and vitamin
