Heme-copper oxidases (HCOs) are terminal enzymes on the mitochondrial or bacterial
respiratory electron transport chain, which utilize a unique heterobinuclear active site to …

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 …

Proton transfer and transport in water, gramicidin and some selected channels and
bioenergetic proteins are reviewed. An attempt is made to draw some conclusions about …

Abstract Electrochemically active Metal‐Organic Frameworks (MOFs) have been
progressively recognized for their use in solar fuel production schemes. Typically, they are …

Cyanobacteria must prevent imbalances between absorbed light energy (source) and the
metabolic capacity (sink) to utilize it to protect their photosynthetic apparatus against …

Competition for molecular oxygen (O2) among respiratory microorganisms is intense
because O2 is a potent electron acceptor. This competition leads to the formation of …

Many chemical and biological processes involve the transfer of both protons and electrons.
The complex mechanistic details of these proton-coupled electron transfer (PCET) reactions …

The respiratory chain or oxidative phosphorylation system (OxPhos) generates most of the
chemical energy (ATP) used by our cells. The cytochrome c oxidase (CcO) is one of three …

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 …

Various oxygen-utilizing electron sinks, including the soluble flavodiiron proteins (Flv1/3),
and the membrane-localized respiratory terminal oxidases (RTO s), cytochrome c oxidase …
