Homogeneous catalytic O2 reduction to water by a cytochrome c oxidase model with trapping of intermediates and mechanistic insights.
An efficient and selective four-electron plus four-proton (4e(-)/4H(+)) reduction of O(2) to water by decamethylferrocene and trifluoroacetic acid can be catalyzed by a synthetic analog of the heme a(3)/Cu(B) site in cytochrome c oxidase ((6)LFeCu) or its Cu-free version ((6)LFe) in acetone. A detailed mechanistic-kinetic study on the homogeneous catalytic system reveals spectroscopically detec...
متن کاملRole of a distal pocket in the catalytic O2 reduction by cytochrome c oxidase models immobilized on interdigitated array electrodes.
Five iron porphyrins with different superstructures were immobilized on self-assembled-monolayer (SAM)-coated interdigitated-array (IDAs) gold-platinum electrodes. The selectivity of the catalysts i.e., limited formation of partially reduced oxygen species (PROS) in the electrocatalytic reduction of dioxygen, is a function of 2 rates: (i) the rate of electron transfer from the electrode to the ...
متن کاملSingle catalytic site model for the oxidation of ferrocytochrome c by mitochondrial cytochrome c oxidase.
A single catalytic site model is proposed to account for the multiphasic kinetics of oxidation of ferrocytochrome c by cytochrome c oxidase (ferrocytochrome c:oxygen oxidoreductase, EC 1.9.3.1). This model involves nonproductive binding of substrate to sites near the catalytic site on cytochrome c oxidase for cytochrome c, decreasing the binding constant for cytochrome c at the catalytic site. ...
متن کاملDual-mode EPR spectrometry of O2-pulsed cytochrome c oxidase.
O2-activated bovine heart cytochrome c oxidase has been examined by dual-mode EPR spectrometry. Resonances have been observed at g = 10 and 4.5 in the parallel mode and at g = 10, 5, 1.8 and 1.7 in the normal mode. The bulk of these signals are interpreted to come from a stoichiometric S = 2 system with magnitude of a = 0.17 cm-1, D = +2.1 cm-1, magnitude of E = 0.026 cm-1, g = 2. Exchange coup...
متن کاملTHE REDUCTION OF CYTOCHROME c BY XANTHINE OXIDASE
A number of substances such as oxygen, dyes, and nitrate can act as hydrogen acceptors for xanthine oxidase (1). It has now been found that cytochrome c is also reduced by this system. Since only one other enzyme has been isolated which reduces cytochrome c (2), it was of interest to study the reaction, particularly since Ball (3) has indicated that xanthine oxidase is a flavoprotein. The activ...
