Yeast cytochrome c peroxidase. Coordination and spin states of heme prosthetic group.

Journal of Biological Chemistry, 1987
Electronic absorption and electron paramagnetic resonance (EPR) spectroscopic examinations revealed that a freshly prepared cytochrome c peroxidase (CCP) contains a penta-coordinated high spin ferric protoheme group. The penta-coordinated high spin state of fresh CCP is maintained in a remarkably wide range of pH (4-8).

Carboxyl group protonation upon reduction of the Paracoccus denitrificans cytochrome c oxidase: direct evidence by FTIR spectroscopy [PDF]

FEBS Letters, 1996
The redox reactions of the cytochrome c oxidase from Paracoccus denitrificans were investigated in a thin‐layer cell designed for the combination of electrochemistry under anaerobic conditions with UVIVIS and IR spectroscopy. Quantitative and reversible electrochemical reactions were obtained at a surface‐modified electrode for all cofactors as ...

The electron distribution in the “activated” state of cytochrome c oxidase

Scientific Reports, 2018
Cytochrome c oxidase catalyzes reduction of O2 to H2O at a catalytic site that is composed of a copper ion and heme group. The reaction is linked to translocation of four protons across the membrane for each O2 reduced to water.

Probing a Complex of Cytochromecand Cardiolipin by Magnetic Circular Dichroism Spectroscopy: Implications for the Initial Events in Apoptosis [PDF]

Journal of the American Chemical Society, 2011
Oxidation of cardiolipin (CL) by its complex with cytochrome c (cyt c) plays a crucial role in triggering apoptosis. Through a combination of magnetic circular dichroism spectroscopy and potentiometric titrations, we show that both the ferric and ferrous

The response of glutathione oxidase and cytochrome c to exercise training and sodium selenite in the heart tissue of male rats [PDF]

Biochemistry and Biophysics Reports
Introduction: Exercise training combined with supplements may be effective in enhancing antioxidant defense and mitochondrial function. Therefore, this study aimed to determine the response of glutathione peroxidase and cytochrome c to forced resistance ...

Effect of Vitis gracilis Wall. administration on maximal swimming exercise apoptosis via cytochrome c in rat lung cells [PDF]

Journal of Pharmacy & Pharmacognosy Research, 2023
Context: The high mortality rate in people with lung disease indicates that this disorder requires immediate attention. It is established that excessive swimming can reduce the ability of lung cells to function and cause respiratory problems.

Phylogenetic and functional analysis of cyanobacterial Cytochrome c6-like proteins

Frontiers in Plant Science, 2023
All known photosynthetic cyanobacteria carry a cytochrome c6 protein that acts transferring electrons from cytochrome b6f complex to photosystem I, in photosynthesis, or cytochrome c oxidase, in respiration.
