Reactive oxygen species (ROS) comprise the superoxide anion (O2•−), hydrogen peroxide
(H2O2), hydroxyl radical (• OH), and singlet oxygen (1O2). ROS can damage a variety of …

Acetic acid bacteria (AAB) are a group of bacteria that can oxidize many substrates such as
alcohols and sugar alcohols and play important roles in industrial biotechnology. A majority …

Cytochrome bd quinol: O2 oxidoreductases are respiratory terminal oxidases so far only
identified in prokaryotes, including several pathogenic bacteria. Escherichia coli contains …

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 …

This review focuses on the effects of hydrogen sulfide (H2S) on the unique bioenergetic
molecular machines in mitochondria and bacteria—the protein complexes of electron …

The production of reactive nitrogen species (RNS) by the innate immune system is part of
the host's defense against invading pathogenic bacteria. In this review, we summarize …

Hydrogen sulfide and carbon monoxide share the ability to be beneficial or harmful
molecules depending on the concentrations to which organisms are exposed. Interestingly …

Terminal respiratory oxidases are highly efficient molecular machines. These most important
bioenergetic membrane enzymes transform the energy of chemical bonds released during …

One of the main functions of enzyme complexes that constitute electron transport
(respiratory) chains of organisms is to maintain cellular redox homeostasis by oxidizing …

Hydrogen sulfide (H 2 S) is often called the third gasotransmitter (after nitric oxide and
carbon monoxide), or endogenous gaseous signaling molecule. This compound plays …
