TL;DR: The crystal structure of the ba3‐cytochrome c oxidase from Thermus thermophilus has been determined to 2.4 Å resolution and the discovery of a novel subunit IIa is led to the identification of sequence motifs and residues that seem to be indispensable for the function of the haem copper oxidases.

TL;DR: Simulations of the EPR spectra indicated that Cu-Cu interaction, in a mixed-valence [Cu(1.5) ... Cu(1/2)], S = 1/2 site is consistent with, if not proof of, the unusual spectral features observed for N2OR and COX.

TL;DR: Dicyclohexylcarbodiimide reacted with beef heart cytochrome c oxidase in inhibit the proton-pumping function of this enzyme and to a lesser extent to inhibit electron transfer.

TL;DR: Metal contents of preparations of procaryotic and eucaryotic cytochrome c oxidases have been determined by inductively coupled plasma atomic emission spectroscopy and shown to be stoichiometrically related to the protein contents.

TL;DR: The findings support the hypothesis of a common phylogeny of aerobic respiration and bacterial denitrification, which was proposed on the basis of structural similarities between the Pseudomonas stutzeri NO reductase and the cbb(3) terminal oxidases, by suggesting a mechanism consistent with the stoichiometry of the overall reaction.
