The cytochrome c peroxidase-catalyzed oxidation of ferrocytochrome c by hydrogen peroxide. Steady state kinetic mechanism.
Initial velocities for the cytochrome c peroxidase-catalyzed oxidation of ferrocytochrome c by hydrogen peroxide have been measured as functions of both the ferrocytochrome c (0.27-104 microM) and hydrogen peroxide (0.25-200 microM) concentrations at 25 degrees C, 0.01 M ionic strength, and pH 7 in a cacodylate/KNO3 buffer system Eadie-Hofstee plots of the initial velocity as a function of ferr...
متن کاملHydrogen peroxide induced oxidation of peroxisomal malate synthase and catalase.
Peroxisomes contain oxidases that produce H(2)O(2), which can result in protein oxidation. To test the vulnerability of peroxisomal proteins to oxidation in vivo the organelles were isolated from castor bean endosperm incubated with H(2)O(2). When peroxisomes were exposed to H(2)O(2)in vivo, the peroxisomal proteins exhibited an increase in carbonylation as detected in avidin blots of biotin hy...
متن کاملHomocysteine Inhibits Hydrogen Peroxide Breakdown by Catalase
Catalase, an antioxidant enzyme responsible for degradation of hydrogen peroxide, is protective in many diseases. The amino-acid homocysteine has been suggested to be a pro-oxidant with elevated levels linked to the oxidative stress seen in Alzheimer’s and other diseases. This study shows that homocysteine inhibits the breakdown of hydrogen peroxide by catalase. Physiological concentrations of ...
متن کاملGlutathione peroxidase-catalase cooperativity is required for resistance to hydrogen peroxide by mature rat oligodendrocytes.
Oxidative mechanisms of injury are important in many neurological disorders, including hypoxic-ischemic brain damage. Cerebral palsy after preterm birth is hypothesized to be caused by hypoxic-ischemic injury of developing oligodendrocytes (OLs). Here we examined the developmental sensitivity of OLs to exogenous hydrogen peroxide (H2O2) with stage-specific rat oligodendrocyte cultures. We found...
متن کاملHydrogen Peroxide-mediated Oxidation of Indole-3-acetic Acid by Tomato Peroxidase and Molecular Oxygen.
The oxidation of indole-3-acetic acid by anionic tomato peroxidase was found to be negligible unless reaction mixtures were supplemented with H(2)O(2). The addition of H(2)O(2) to reaction mixtures initiated a period of rapid indole-3-acetic acid oxidation and O(2) uptake; this phase ended and O(2) uptake fell to a low level when the H(2)O(2) was exhausted. The stoichiometry of the reaction, wh...
