EPR and solid-state NMR studies on the mechanism of cytochrome bo3 ubiquinol oxidase from escherichia coli
Cytochrome bo3 ubiquinol oxidase from E. coli is a member of heme-copper oxidase superfamily. This trans-membrane enzyme complex catalyzes two-electron oxidation of ubiquinol and reduction of molecular oxygen to water. During the process, the protons from ubiquinol are released to the periplasmic …

Structural and Functional Studies on Cytochrome BO3 Ubiquinol Oxidase From Escherichia Coli and the Characterization of Its Quinone Binding Sites
Cytochrome bo3 ubiquinol oxidase is the terminal oxidase in the aerobic respiratory chain of Escherichia coli. The enzyme catalyzes the oxidation of ubiquinol-8 and the reduction of oxygen to water, which are coupled to the translocation of protons across the cytoplasmic membrane via protolytic …

Studies on the structure, function and mechanisms of the cbb3 type cytochrome c oxidase from Vibrio cholerae and the cytochrome bo3 ubiquinol oxidase from Escherichia coli
Cytochrome c oxidases (CcO) are terminal oxidases in the respiratory chain and contribute to a large fraction in the heme-copper oxidase superfamily. They are transmembrane protein complexes catalyzing the reduction of dioxygen to water with a variety range of electron donors. During the process, …

Solid-state NMR studies of membrane proteins and membrane protein complexes
… SSNMR techniques are used to study a 144 kDa cytochrome bo3 ubiquinol oxidase demonstrating the power of this technique to investigate large membrane complexes in native environments.

Biochemical characterization of a-type heme-copper oxidases in escherichia coli, bacillus subtilis and thermus thermophilus
Heme-copper oxidases (HCOs) couple the free energy of oxygen reduction and translocate protons across membrane to generate a proton electrochemical gradient, which was used to produce ATP by ATP synthase. Based on the sequences and structures of core subunits, they are classified into 3 types. …
