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 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.

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.

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-

The oxidation of cytochrome c by cytochrome c peroxidase
Archives of Biochemistry and Biophysics, 1960Abstract 1. 1. The reaction between cytochrome c and cytochrome c peroxidase is first order in cytochrome c. 2. 2. The reaction is inhibited by both oxidized and reduced cytochrome c. 3. 3. The dependence of the reaction rate on ionic strength suggests that the reaction occurs at oppositely charged active sites on the two proteins. 4.
