The low-affinity complex of cytochrome c and its peroxidase [PDF]
Nature Communications, 2015 The complex of yeast cytochrome c peroxidase and cytochrome c is a paradigm of the biological electron transfer (ET). Building on seven decades of research, two different models have been proposed to explain its functional redox activity.

Studies on Cytochrome c Peroxidase [PDF]
Journal of Biological Chemistry, 1969 Abstract Protoporphyrin monomethyl ester and protoheme monomethyl ester were recombined with apocytochrome c per-oxidase. The iron-free porphyrin-protein complex has absorption maxima at 408, 511, 547, 576, and 629 nm. The complex has no peroxidase activity. The protoheme monomethyl ester complex reacts with a stoichiometric amount of hydrogen peroxide

Studies on Cytochrome c Peroxidase
Journal of Biological Chemistry, 1967 Abstract The reaction of ferrimyoglobin with H2O2 was investigated by a combination of spectrophotometric and electron paramagnetic resonance measurements and enzymic assay of of hydroperoxide by the cytochrome c peroxidase system. On the addition of an excess of H2O2 to ferrimyoglobin, approximately 1.5 moles of H2O2 were consumed per mole of the ...

Biomolecules, 2022 A key event in the cytochrome c-dependent apoptotic pathway is the permeabilization of the outer mitochondrial membrane, resulting in the release of various apoptogenic factors, including cytochrome c, into the cytosol.

Kinetic and equilibrium studies of acrylonitrile binding to cytochrome c peroxidase and oxidation of acrylonitrile by cytochrome c peroxidase compound I. [PDF]
Biochem Biophys Res Commun, 2014 Ferric heme proteins bind weakly basic ligands and the binding affinity is often pH dependent due to protonation of the ligand as well as the protein. In an effort to find a small, neutral ligand without significant acid/base properties to probe ligand binding reactions in ferric heme proteins we were led to consider the organonitriles.

Peroxidase Activity of Cytochrome c [PDF]
Bulletin of the Korean Chemical Society, 2004 , deferoxamine (DFX)and ethylenediamine tetraacetic acid (EDTA) were pur-chased from Sigma. The diammonium salt of 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulfonate) (ABTS) was obtainedfrom Boehringer Mannheim. Chelex 100 resin (sodiumform) was obtained from Bio-Rad. All materials weretreated with Chelex 100 resin.
