Hyperoxia results in increased aerobic metabolism following acute brain injury [PDF]

, 2016
Acute brain injury is associated with depressed aerobic metabolism. Below a critical mitochondrial pO2 cytochrome c oxidase, the terminal electron acceptor in the mitochondrial respiratory chain, fails to sustain oxidative phosphorylation.

Sulfite oxidase activity of cytochrome c: Role of hydrogen peroxide

Biochemistry and Biophysics Reports, 2016
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.

Cytochrome c oxidase in prokaryotes [PDF]

FEMS Microbiology Letters, 1987
Several heme aa3-type cytochrome c oxidases, purified from the cytoplasmic membranes of bacteria, are able to catalyze the same reactions as the structurally far more complex eukaryotic enzyme, i.e., electron transport from cytochrome c to oxygen coupled to proton translocation.

Observation of Catalytic Variability of Single Enzyme Zeolitic Imidazole Framework‐8 Nanoparticles

Advanced Materials Interfaces, EarlyView.
A microwell‐based fluorescence method characterizes the catalytic activity of single enzyme zeolitic imidazole framework‐8 (ZIF‐8) nanoparticles (NPs). Horseradish peroxidase (HRP) and bovine serum albumin (BSA) are loaded into ZIF‐8 NPs and reveal subpopulations of catalytic activity at single‐particle resolution.

Evolution of the Couple Cytochrome c and Cytochrome c Oxidase in Primates [PDF]

, 2012
Mitochondrial energy metabolism has been affected by a broad set of ancient and recent evolutionary events. The oldest example is the endosymbiosis theory that led to mitochondria and a recently proposed example is adaptation to cold climate by anatomically modern human lineages.

Melatonin Modulates Glucose Metabolism Reprogramming via Targeting G6PD to Alleviate Lead‐Induced Hepatocytes Pyroptosis in Common Carp (Cyprinus carpio L.)

Advanced Science, EarlyView.
This study reveals that Lead reprograms glucose metabolism to enhance H3K18la, driving DRP1‐dependent mitochondrial DNA leakage and cGAS‐STING‐mediated pyroptosis. Melatonin targets G6PD to suppress glycolysis‐driven H3K18la and restore mitochondrial homeostasis, thereby alleviating Lead‐induced liver injury in common carp through disruption of the ...

Proton-transfer pathways in the mitochondrial S. cerevisiae cytochrome c oxidase

Scientific Reports, 2019
In cytochrome c oxidase (CytcO) reduction of O2 to water is linked to uptake of eight protons from the negative side of the membrane: four are substrate protons used to form water and four are pumped across the membrane.

Cytochrome c: Surfing Off of the Mitochondrial Membrane on the Tops of Complexes III and IV [PDF]

, 2019
The proper arrangement of protein components within the respiratory electron transport chain is nowadays a matter of intense debate, since altering it leads to cell aging and other related pathologies.

Mesencephalic Astrocyte‐Derived Neurotrophic Factor Binds BAX to Preserve Mitochondrial Homeostasis and Energy Metabolism for Relieving Myocardial Hypertrophy

Advanced Science, EarlyView.
MANF in cardiomyocytes interacts with BAX to impede BAX mitochondrial translocation and cytochrome c release, further stabilizing mitochondrial structure and energy supply to relieve myocardial apoptosis and hypertrophy, which indicates MANF as a novel cardioprotective factor to have a promising clinical application for myocardial hypertrophy ...
