How Hydrogen Peroxide Is Metabolized by Oxidized Cytochrome c Oxidase
In the absence of external electron donors, oxidized bovine cytochrome c oxidase (CcO) exhibits the ability to decompose excess H2O2. Depending on the concentration of peroxide, two mechanisms of degradation were identified. At submillimolar peroxide concentrations, decomposition proceeds with virtually no production of superoxide and oxygen. In contrast, in the millimolar H2O2 concentration ra...
متن کاملThe reaction of hydrogen peroxide with the dimethyl ester heme derivative of cytochrome c peroxidase.
A modified cytochrome c peroxidase was prepared by reconstituting apocytochrome c peroxidase with protoheme in which both heme propionic acid groups were converted to the methyl ester derivatives. The modified enzyme reacted with hydrogen peroxide with a rate constant of (1.3 +/- 0.2) x 10(7) M-1 s-1, which is 28% that of the native enzyme. The reaction between the modified enzyme and hydrogen ...

[ 22 ] Thus, given the widespread presence of H 2 O 2 in the body and environment, and the future impact graphene may have on human health and environment, systematic studies need to be performed to investigate the direct chemical interaction between H 2 O 2 and graphe...
متن کاملSulfite oxidase activity of cytochrome c: Role of hydrogen peroxide
In humans, sulfite is generated endogenously by the metabolism of sulfur containing amino acids such as methionine and cysteine. Sulfite is also formed from exposure to sulfur dioxide, one of the major environmental pollutants. Sulfite is used as an antioxidant and preservative in dried fruits, vegetables, and beverages such as wine. Sulfite is also used as a stabilizer in many drugs. Sulfite t...
متن کاملMechanism of the biomolecular synthesis of PEDOT:PSS: importance of heme degradation by hydrogen peroxide.
UNLABELLED The use of biomolecules as oxidants for the synthesis of conducting polymers provides an important tool for the control of polymer properties. Using PEDOT PSS as a representative conducting polymer, we compare a set of heme proteins (soybean peroxidase, cytochrome c, and horseradish peroxidase) used as oxidants. The resulting PEDOT PSS was characterized with visible and near IR s...
