Rcf1 Modulates Cytochrome c Oxidase Activity Especially Under Energy-Demanding Conditions [PDF]

open access: goldFrontiers in Physiology, 2020
The mitochondrial respiratory chain is assembled into supercomplexes. Previously, two respiratory supercomplex-associated proteins, Rcf1 and Rcf2, were identified in Saccharomyces cerevisiae, which were initially suggested to mediate supercomplex ...

Copper-Induced Enhancement of Glioblastoma Tumorigenicity via Cytochrome C Oxidase [PDF]

open access: yesAntioxidants
Copper is an essential trace element, yet chronic copper exposure can lead to toxicity in humans, and high levels of copper have been found in the blood or tumors of patients with various forms of cancer and may affect cancer severity and response to ...

Stability of Bovine Cytochrome c Oxidase as Studied After Exposure to High Hydrostatic Pressure [PDF]

open access: diamondActa Medica, 2004
Structural and functional stability of bovine cytochrome c oxidase as a function of exposure to high hydrostatic pressure is reported. The pressure affects the stability of monomeric and dimeric enzyme quite differently.

Multiple Mechanisms Regulate Eukaryotic Cytochrome C Oxidase

open access: yesCells, 2021
Cytochrome c oxidase (COX), the rate-limiting enzyme of mitochondrial respiration, is regulated by various mechanisms. Its regulation by ATP (adenosine triphosphate) appears of particular importance, since it evolved early during evolution and is still ...

Cytochrome c Oxidase Deficiency [PDF]

open access: yesPediatric Research, 1990
Cytochrome c oxidase (COX) is a complex enzyme composed of 13 subunits, three of which are encoded by the mitochondrial DNA (mtDNA). The other 10 subunits are encoded by the nuclear DNA, synthesized in the cytoplasm, and transported into the mitochondria.

Cytochrome c oxidase deficiency

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2021
Cytochrome c oxidase (COX) deficiency is characterized by a high degree of genetic and phenotypic heterogeneity, partly reflecting the extreme structural complexity, multiple post-translational modification, variable, tissue-specific composition, and the high number of and intricate connections among the assembly factors of this enzyme.

Cryo-EM structures of intermediates suggest an alternative catalytic reaction cycle for cytochrome c oxidase

open access: yesNature Communications, 2021
Cytochrome c oxidase is a fundamental enzyme of life and its mechanism is not fully understood yet. Here, the authors present four cryo-EM structures of different intermediate states, which suggest an alternative cytochrome c oxidase reaction cycle.

Multilayered polyelectrolyte microcapsules: interaction with the enzyme cytochrome C oxidase. [PDF]

open access: yesPLoS ONE, 2014
Cell-sized polyelectrolyte capsules functionalized with a redox-driven proton pump protein were assembled for the first time. The interaction of polyelectrolyte microcapsules, fabricated by electrostatic layer-by-layer assembly, with cytochrome c oxidase

Activity of respiratory chain cytochrome complexes and cytochromes content in the rat kidney mitochondria under different nutrients content in a diet [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2023
An important role in ensuring the functioning of the respiratory chain belongs to the cytochrome part, which includes complexes III (ubiquinol-cytochrome c oxidoreductase) and IV (cytochrome c oxidase). The key components of these enzymatic complexes are
