Current Opinion in Structural Biology, 1996
Within the past year, the structures of the cytochrome c oxidase from the soil bacterium Paracoccus denitrificans and of the metal centers of the cytochrome c oxidase from bovine heart mitochondria, both determined at 2.8 A resolution by X-ray crystallography, have been reported. The structures form a basis for understanding the mechanism of this redox-

Journal of Inorganic Biochemistry, 1985
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 ...

Biogenesis of cytochrome c oxidase
Mitochondrion, 2005Cytochrome c oxidase (COX), the terminal enzyme of electron transport chains in some prokaryotes and in mitochondria, has been characterized in detail over many years. Recently, a number of new data on structural and functional aspects as well as on COX biogenesis emerged.

Reactions of mercaptans with cytochrome c oxidase and cytochrome c
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 19801. The steady-state oxidation of ferrocytochrome c by dioxygen catalyzed by cytochrome c oxidase, is inhibited non-competitively towards cytochrome c by methanethiol, ethanethiol, 1-propanethiol and 1-butanethiol with Ki values of 4.5, 91, 200 and 330 microM, respectively. 2.

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 .

The cytochrome c binding site on cytochrome c oxidase
Biochemical and Biophysical Research Communications, 1979Abstract Cytochrome c was chemically coupled to cytochrome c oxidase using the reagent 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) which couples amine groups to carboxyl residues. The products of this reaction were analyzed on 2.5–27% polyacrylamide gradient gels electrophoretically.

Charge interactions of cytochrome c with cytochrome c oxidase
International Journal of Biochemistry, 1984The pyridoxal phosphate (PLP) modification of the lysine amino groups in cytochrome c causes decrease in the reaction rate with cytochrome c oxidase. The rate constants for (PLP)2-cyt. c, PLP(Lys 86)-cyt. c, PLP(Lys 79)-cyt. c and native cytochrome c (at pH 7.4, I = 0.02) are 3.6 X 10(-3) sec-1, 5.5 X 10(-3) sec-1, 5.2 X 10(-3) sec-1 and 9.8 X 10(-3 ...

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.

Structure of Cytochrome c Oxidase
1980Cytochrome c oxidase or cytochrome c : oxygen oxidoreductase (CH 1.9.3.1) is the terminal oxidase in respiratory metabolism of all aerobic organisms and is responsible for catalyzing the reduction of dioxygen to water in the reaction: $$ 4{H^ + } + 4{e^ - } + {O_2} \rightleftarrows 2{H_2}O $$ The electrons for this reaction are provided by ...
