Cytochrome a and Cytochrome Oxidase
Nature, 1938A HEART muscle preparation obtained by a method previously described1 contains several dehydrogenases, a very powerful cytochrome oxidase and the three components (a, b, and c) of cytochrome. This material contains a high concentration of cytochrome a and is therefore very suitable for the study of this component.

The identification of two functionally distinct states, called pulsed and resting, has led to a number of investigations on the conformational variants of the enzyme. However, the catalytic properties of cytochrome oxidase may depend on a number of experimental conditions related to the solvent as well as to the protocol followed to determine the ...

Cytochrome oxidase is the terminal oxidase of most of aerobic organisms and reduces molecular oxygen (O2) to water (1). The electrons and protons required for the formation of water molecules are transferred from both sides of the mitochondrial inner membranes in eukaryotic cells and of the cell membrane in prokaryotic cells (1).

Association of cardiolipin and cytochrome oxidase
Biochemical and Biophysical Research Communications, 1970Abstract A small amount of cardiolipin (diphosphatidyl glycerol) is tightly bound to cytochrome oxidase. The stoichiometry approaches one molecule of cardiolipin per molecule of cytochrome a. Solvent extraction and phospholipase treatments which remove or destroy other phospholipids and the bulk cardiolipin do not effect this tightly bound ...

Cytochrome oxidase in health and disease
Gene, 2002Yeast and bovine cytochrome c oxidases (COX) are composed of 12 and 13 different polypeptides, respectively. In both cases, the three subunits constituting the catalytic core are encoded by mitochondrial DNA. The other subunits are all products of nuclear genes that are translated on cytoplasmic ribosomes and imported through different transport routes

The kinetics of cytochrome c oxidase I. The system: Cytochrome c-cytochrome oxidase-oxygen
Biochimica et Biophysica Acta, 1961Abstract 1. 1. The kinetics of cytochrome c oxidase were studied in the Keilin and Hartree heart-muscle preparation by measuring the disappearance of reduced cytochrome c spectrophotometrically. The results of Smith and Conrad were confirmed. 2. 2.

Studies on the resolution of cytochrome oxidase
Journal of Bioenergetics and Biomembranes, 1981Cytochrome oxidase has been resolved in acetic acid and high salt/detergent media. In 0.5% acetic acid, the smaller subunits of the enzyme are selectively extracted with retention of an insoluble protein fraction containing subunits I-IV, VII. This fraction retains all the heme and copper of the original enzyme in a spectrally unaltered state, and ...

Cytochrome c oxidase deficiency
2002Publisher Summary Cytochrome c oxidase (COX) is the terminal component (complex IV) of the mitochondrial respiratory chain, the main energy-generating system of eukaryotic cells. COX-synthetic pathways have been derived from biochemical and genetic studies of respiratory-defective petite mutants of Saccharomyces cerevisiae .
