The nature of CuA in cytochrome c oxidase.
Journal of Biological Chemistry, 1982 The isolation and purification of yeast cytochrome c oxidase is described. Characterization of the purified protein indicates that it is spectroscopically identical with cytochrome c oxidase isolated from beef heart. Preparations of isotopically substituted yeast cytochrome c oxidase are obtained incorporating [1,3-15N2]histidine or [beta,beta-2H2 ...

Reinforcing Stromal Cell Spheroid Through Red‐Light Preconditioning for Advanced Vascularization
Advanced Science, EarlyView.This study presents a novel approach to enhance stromal cell therapy for myocardial infarction by combining OLED‐based photobiomodulation (OPBM) preconditioning with 3D spheroid culture of hADSCs. The engineered spheroids improve angiogenesis, arterialization, and cardiac function in vivo, offering a next‐generation therapeutic strategy to overcome ...

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.

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.

Scientific Reports, 2013 The respiratory chain or oxidative phosphorylation system (OxPhos) generates most of the chemical energy (ATP) used by our cells. The cytochrome c oxidase (CcO) is one of three protein complexes of OxPhos building up a proton gradient across the inner ...

Advanced Science, EarlyView.Abnormal mechanical stretch induced by mechanical ventilation (MV) disrupts endothelial junctions via the NOX2/ROS/CaMKII/ERK1/2 axis both in human aortic endothelial cells (HAECs) in vitro and in ventilator‐induced lung injury (VILI) in mice. Quercetin, an antioxidant predicted to bind to NOX2, can effectively prevent mechanical stretch‐induced ...

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.
