Study of the Proton Pumping Mechanism of the Aa3-Type Cytochrome C Oxidase
Cytochrome c oxidase is the last component of the respiratory chains. It accepts electrons from a water-soluble or membrane-anchored cytochrome c and catalyzes the reduction of O2 to water (O2 + 4e- + 4H+ → 2 H2O). In cytochrome aa3 oxidase (C cO), electrons from cytochrome c are first …

Microscopic description of gas permeation and delivery pathways in biological macromolecules
… CO2 in aerobic respiratory terminal oxidases (cytochrome ba3 and cytochrome aa3), nitric oxide reductase (cNOR) and bacterial carboxysome, and to describe the movement of O2, CO2 and NH3 through lipid membranes and membrane channels. In the first part of this dissertation, I illustrated the …

Biochemical characterization of a-type heme-copper oxidases in escherichia coli, bacillus subtilis and thermus thermophilus
… by far the most abundant including mitochondrial cytochrome c oxidase and its close homologs. Over the years, great efforts have been invested to study the function of A-type oxidases. A highly conserved glutamic acid residue has been proved to be the branch point for proton translocation, …

The interactions of cytochrome bo3 from Escherichia coli with its substrates - ubiquinone and oxygen
… oxidation of ubiquinol or menaquinol instead of cytochrome c. Escherichia coli (E. coli) cytochrome bo3 is the best characterized quinol oxidase. Depending on the detergent used to solubilize the enzyme, cyt bo3, preparations of this enzyme contain between 0 to 2 equivalents of ubiquinone-8. …
