Phylogenetic and functional analysis of cyanobacterial Cytochrome c6-like proteins
Frontiers in Plant Science, 2023 All known photosynthetic cyanobacteria carry a cytochrome c6 protein that acts transferring electrons from cytochrome b6f complex to photosystem I, in photosynthesis, or cytochrome c oxidase, in respiration.

Redox-controlled proton gating in bovine cytochrome c oxidase. [PDF]
PLoS ONE, 2013 Cytochrome c oxidase is the terminal enzyme in the electron transfer chain of essentially all organisms that utilize oxygen to generate energy. It reduces oxygen to water and harnesses the energy to pump protons across the mitochondrial membrane in ...

Structure of yeast cytochrome c oxidase in a supercomplex with cytochrome bc1
Nature Structural & Molecular Biology, 2018 Cytochrome c oxidase (complex IV, CIV) is known in mammals to exist independently or in association with other respiratory proteins to form supercomplexes (SCs).

Interaction of Cytochrome C Oxidase with Steroid Hormones
Cells, 2020 Estradiol, testosterone and other steroid hormones inhibit cytochrome c oxidase (CcO) purified from bovine heart. The inhibition is strongly dependent on concentration of dodecyl-maltoside (DM) in the assay.

Oxygen Activation and Energy Conservation by Cytochrome c Oxidase
Chemical Reviews, 2018 This review focuses on the type A cytochrome c oxidases (CcO), which are found in all mitochondria and also in several aerobic bacteria. CcO catalyzes the respiratory reduction of dioxygen (O2) to water by an intriguing mechanism, the details of which ...

Mechanical ventilation preserves diaphragm mitochondrial function in a rat sepsis model
Intensive Care Medicine Experimental, 2021 Background To describe the effect of mechanical ventilation on diaphragm mitochondrial oxygen consumption, ATP production, reactive oxygen species (ROS) generation, and cytochrome c oxidase activity and content, and their relationship to diaphragm ...

New insight into the mechanism of mitochondrial cytochrome c function. [PDF]
PLoS ONE, 2017 We investigate functional role of the P76GTKMIFA83 fragment of the primary structure of cytochrome c. Based on the data obtained by the analysis of informational structure (ANIS), we propose a model of functioning of cytochrome c. According to this model,
