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 …

Pathogens that infect the gastrointestinal and respiratory tracts are subjected to intense
pressure due to the environmental conditions of the surroundings. This pressure has led to …

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 …

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

Mitochondrial cytochrome c oxidase is a member of a diverse superfamily of haem–copper
oxidases. Its mechanism of oxygen reduction is reviewed in terms of the cycle of catalytic …

Evolutionary histories of enzymes involved in chemiosmotic energy conversion indicate that
a strongly oxidizing substrate was available to the last universal common ancestor before …

Recent time-resolved optical and electrometric experiments have provided a sequence of
events for the proton-translocating mechanism of cytochrome c oxidase. These data also set …

Membrane bound respiratory complex I is the key enzyme in the respiratory chains of
bacteria and mitochondria, and couples the reduction of quinone to the pumping of protons …

Shewanella are renowned for their ability to utilize a wide range of electron acceptors (EA)
for respiration, which has been partially accredited to the presence of a large number of the …

Bacteria can colonize virtually any environment on Earth due to their remarkable capacity to
detect and respond quickly and adequately to environmental stressors. Vibrio cholerae is a …
