Electrostatic interaction of cytochrome c with cytochrome c1 and cytochrome oxidase.
The reactions of horse heart cytochrome c with succinate-cytochrome c reductase and cytochrome oxidase were studied as a function of ionic strength using both spectrophotometric and oxygen electrode assay techniques. The kinetic parameter Vmax/Km for both reactions decreased very rapidly as the ionic strength was increased, indicating that ...

Cytochrome c signalosome in mitochondria [PDF]
Cytochrome c delicately tilts the balance between cell life (respiration) and cell death (apoptosis). Whereas cell life is governed by transient electron transfer interactions of cytochrome c inside the mitochondria, the cytoplasmic adducts of cytochrome

Oxidative stress is tightly regulated by cytochrome c phosphorylation and respirasome factors in mitochondria [PDF]
Respiratory cytochrome c has been found to be phosphorylated at tyrosine 97 in the postischemic brain upon neuroprotective insulin treatment, but how such posttranslational modification affects mitochondrial metabolism is unclear.

Rcf1 and Rcf2, Members of the Hypoxia-induced Gene 1 Protein Family, Are Critical Components of the Mitochondrial Cytochrome bc1-cytochrome Oxidase Supercomplex [PDF]
We report that Rcf1 (formerly Aim31), a member of the conserved hypoxia-induced gene 1 (Hig1) protein family, represents a novel component of the yeast cytochrome bc1-cytochrome c oxidase (COX) supercomplex.

The role of a disulfide bridge in the stability and folding kinetics of Arabidopsis thaliana cytochrome c6A [PDF]
Cytochrome c 6A is a eukaryotic member of the Class I cytochrome c family possessing a high structural homology with photosynthetic cytochrome c 6 from cyanobacteria, but structurally and functionally distinct through the presence of a disulfide bond and

Murburn concept: a paradigm shift in cellular metabolism and physiology
Two decades of evidence-based exploratory pursuits in heme-flavin enzymology led to the formulation of a new biological electron/moiety transfer paradigm, called murburn concept.

Cytochrome c binding affects the conformation of cytochrome a in cytochrome c oxidase.
Second derivative absorption spectroscopy has been used to assess the effects of complex formation between cytochrome c and cytochrome c oxidase on the conformation of the cytochrome a cofactor. When ferrocytochrome c is complexed to the cyanide-inhibited reduced or mixed valence enzyme, the conformation of ferrocytochrome a is affected.

Early steps in mitochondrial protein import [PDF]
The process of insertion of precursor proteins into mitochondrial membranes was investigated using a hybrid protein (pSc1-c) that contains dual targeting information and, at the same time, membrane insertion activity.
