A biochemical approach to study the role of the terminal oxidases in aerobic respiration in Shewanella oneidensis MR-1. [PDF]

PLoS ONE, 2014
The genome of the facultative anaerobic γ-proteobacterium Shewanella oneidensis MR-1 encodes for three terminal oxidases: a bd-type quinol oxidase and two heme-copper oxidases, a A-type cytochrome c oxidase and a cbb 3-type oxidase.

Cholate Disrupts Regulatory Functions of Cytochrome c Oxidase

Cells, 2021
Cytochrome c oxidase (CytOx), the oxygen-accepting and rate-limiting enzyme of mitochondrial respiration, binds with 10 molecules of ADP, 7 of which are exchanged by ATP at high ATP/ADP-ratios.

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 ...

Perturbation of Cytochrome c Maturation Reveals Adaptability of the Respiratory Chain in Mycobacterium tuberculosis

mBio, 2013
Mycobacterium tuberculosis depends on aerobic respiration for growth and utilizes an aa3-type cytochrome c oxidase for terminal electron transfer. Cytochrome c maturation in bacteria requires covalent attachment of heme to apocytochrome c, which occurs ...

Functional and Biogenetical Heterogeneity of the Inner Membrane of Rat-Liver Mitochondria [PDF]

, 1971
Rat liver mitochondria were fragmented by a combined technique of swelling, shrinking, and sonication. Fragments of inner membrane were separated by density gradient centrifugation.

Cytochromes c550, c552, c1 in the electron transport network of Paracoccus denitrificans: redundant or subtly different in function? [PDF]

, 2001
Paracoccus denitrificans strains with mutations in the genes encoding the cytochrome c550, c552, or c1 and in combinations of these genes were constructed, and their growth characteristics were determined.
