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.

A study of the kinetics of the oxidation of cytochrome c by cytochrome c oxidase
Archives of Biochemistry and Biophysics, 1956Abstract 1. 1. The kinetics of the oxidation of ferrocytochrome c by cytochrome c oxidase were studied spectrophotometrically by observing the rate of decrease in optical density at the α, β, or γ band of ferrocytochrome c as the reduced cytochrome c is oxidized. 2. 2.

Brownian Dynamics of Cytochrome c and Cytochrome c Peroxidase Association
Science, 1988Brownian dynamics computer simulations of the diffusional association of electron transport proteins cytochrome c (cyt c) and cytochrome c peroxidase (cyt c per) were performed. A highly detailed and realistic model of the protein structures and their electrostatic interactions was used that was based on an atomic-level spatial description.

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).

The Effect of Trifluoroacetyl-Cytochromecon the Cytochromec/CytochromecOxidase Reaction
Hoppe-Seyler´s Zeitschrift für physiologische Chemie, 1981The importance of electrostatic interactions to the reaction between cytochrome c and cytochrome c oxidase is indicated most directly by the rapid increase in Km as ionic strength is increased. However, Chessa et al. (1980, Hoppe-Seyler's Z. Physiol. Chem. 361, 1077--1091) have recently found that a cytochrome c derivative trifluoroacetylated at all 19

Cytochrome c Peroxidase–Cytochrome c Complexes
2015The yeast cytochrome c peroxidase (CCP)–cytochrome c (cytc) electron transfer system has been critically important in deciphering the molecular level details of protein–protein interactions and electron transfer. The crystal structure of the CCP–cytc together with a number mutagenesis, enzymological, and spectroscopic studies have provided a detailed ...

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 ...

Cytochromes c and Cytochrome c Containing Enzymes
1985Porphyrin-containing compounds fulfil many different roles in biological systems. Broadly speaking, they fall into two main categories. There are the carrier molecules in which the substance carried is either oxygen, as in the case of the haemoglobins and myoglobins, or electrons, as in the cytochromes.
