Circular dichroism studies on native and artificial horseradish peroxidases.
The circular dichroism spectra of native and recombined vinyl-(protojhematin horseradish peroxidase are identical, which confirms the proper position of the reintroduced group. The same observation and conclusion applies to the light absorption spectra. Circular dichroism and light absorption spectra of seven artificial peroxidases, prepared from apoperoxidase and 2,4substituted hematins, have ...
متن کاملCommon phylogeny of catalase-peroxidases and ascorbate peroxidases.
Catalase-peroxidases belong to Class I of the plant, fungal, bacterial peroxidase superfamily, together with yeast cytochrome c peroxidase and ascorbate peroxidases. Obviously these bifunctional enzymes arose via gene duplication of an ancestral hydroperoxidase. A 230-residues long homologous region exists in all eukaryotic members of Class I, which is present twice in both prokaryotic and arch...
متن کاملA review on plant peroxidases
Plant peroxidase (EC: 1.11.1.7) a heme-containing protein which is widely used in plants, microorganisms and animals. This two - substrate enzyme, catalyze the hydrogen peroxide into water with oxidation of many organic and inorganic substrates that all of them can be used to measure enzyme activity. Although it’s specific substrate is hydrogen peroxide. Calcium and at least four disulfide bo...
متن کاملNanostructures for peroxidases
Peroxidases are enzymes catalyzing redox reactions that cleave peroxides. Their active redox centers have heme, cysteine thiols, selenium, manganese, and other chemical moieties. Peroxidases and their mimetic systems have several technological and biomedical applications such as environment protection, energy production, bioremediation, sensors and immunoassays design, and drug delivery devices...
متن کاملHaem iron-containing peroxidases.
Peroxidases are enzymes that utilize hydrogen peroxide to oxidize substrates. A histidine residue on the proximal side of the haem iron ligates most peroxidases. The various oxidation states and ligand complexes have been spectroscopically characterized. HRP-I is two oxidation states above ferric HRP. It contains an oxoferryl (= oxyferryl) iron with a pi-radical cation that resides on the haem....
