Bacteria power their energy metabolism using membrane-bound respiratory enzymes that
capture chemical energy and transduce it by pumping protons or Na+ ions across their cell …

Activation and reduction of O2 and H2O2 by synthetic and biosynthetic iron porphyrin
models have proved to be a versatile platform for evaluating second-sphere effects deemed …

This review focuses on the type A cytochrome c oxidases (C c O), which are found in all
mitochondria and also in several aerobic bacteria. C c O catalyzes the respiratory reduction …

Cytochrome c oxidase (CcO), the terminal oxidase of cell respiration, reduces molecular
oxygen (O2) in a reaction that is coupled with proton pumping. Since the discovery of this …

Cytochrome bd is a respiratory quinol: O2 oxidoreductase found in many prokaryotes,
including a number of pathogens. The main bioenergetic function of the enzyme is the …

Cellular respiration has a long research history at the interface between biology, chemistry,
and physics. Research in this field spans the entire range from fundamental mechanistic and …

Cytochrome c oxidase (C c O) is part of the respiratory chain and contributes to the
electrochemical membrane gradient in mitochondria as well as in many bacteria, as it uses …

The heme-copper oxidases (HCOs) accomplish the key event of aerobic respiration; they
couple O2 reduction and transmembrane proton pumping. To gain new insights into the still …

Heme–copper oxygen reductases (HCO) reduce O2 to water being the last enzymatic
complexes of most aerobic respiratory chains. These enzymes promote energy conservation …

Heme–copper oxidases (HCO), nitric oxide reductases (NOR), and sulfite reductases (SiR)
catalyze the multi-electron and multi-proton reductions of O2, NO, and SO32−, respectively …
