On the basis of its generally accessible I/II redox couple and bioavailability, copper plays a
wide variety of roles in nature that mostly involve electron transfer (ET), O 2 binding …

Coupled electron and proton transfer reactions play a key role in the mechanisms of
biological energy transduction. 1-3 Such reactions are also fundamental for artificial …

Background Channels and pores in biomacromolecules (proteins, nucleic acids and their
complexes) play significant biological roles, eg, in molecular recognition and enzyme …

The chapter provides a review of the state of art of the oxidative phosphorylation system in
mammalian mitochondria. The sections of the paper deal with:(i) the respiratory chain as a …

We report a supramolecular strategy for promoting the selective reduction of O2 for direct
electrosynthesis of H2O2. We utilized cobalt tetraphenylporphyrin (Co‐TPP), an oxygen …

Cytochrome bd is a prokaryotic respiratory quinol: O 2 oxidoreductase, phylogenetically
unrelated to the extensively studied heme–copper oxidases (HCOs). The enzyme …

Histidine structure and chemistry lie at the heart of many enzyme active sites, ion channels,
and metalloproteins. While solid-state NMR spectroscopy has been used to study histidine …

Voltage-gated proton channels (HV) are unique, in part because the ion they conduct is
unique. HV channels are perfectly selective for protons and have a very small unitary …

Significance: Cytochrome bd is a ubiquinol: oxygen oxidoreductase of many prokaryotic
respiratory chains with a unique structure and functional characteristics. Its primary role is to …

Energy conversion in aerobic organisms involves an electron current from low-potential
donors, such as NADH and succinate, to dioxygen through the membrane-bound respiratory …
