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 ...

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.

An effective long-range attraction between protein molecules in solutions studied by small angle neutron scattering [PDF]
, 2005 Small angle neutron scattering intensity distributions taken from cytochrome C and lysozyme protein solutions show a rising intensity at very small wave vector, Q, which can be interpreted in terms of the presence of a weak long-range attraction between protein molecules.

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.

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 ...

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.

Food Science &Nutrition, Volume 11, Issue 1, Page 39-56, January 2023., 2023 Rutin is a flavonoid present in many plant species. Because of its antioxidant, anti‐inflammatory, and anti‐apoptotic properties, rutin is of interest for its potential protective effects against toxic agents. Rutin has potential therapeutic effectiveness against several toxicants, and its beneficial effects are more than likely mediated by its ...

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.

Local Unsupervised Learning for Image Analysis [PDF]
arXiv, 2019 Local Hebbian learning is believed to be inferior in performance to end-to-end training using a backpropagation algorithm. We question this popular belief by designing a local algorithm that can learn convolutional filters at scale on large image datasets.
