Classically, superoxide anion O2•− and reactive oxygen species ROS play a dual role. At
the physiological balance level, they are a by-product of O2 reduction, necessary for cell …

Reactive oxygen species (ROS) are generated as by-products of normal cellular metabolic
activities. Superoxide dismutase, glutathione peroxidase, and catalase are the enzymes …

Superoxide, O2•−, is formed in all living organisms that come in contact with air, and,
depending upon its biological context, it may act as a signaling agent, a toxic species, or a …

Dissimilatory sulphate reduction is the unifying and defining trait of sulphate-reducing
prokaryotes (SRP). In their predominant habitats, sulphate-rich marine sediments, SRP have …

The photosystem II core complex is the water: plastoquinone oxidoreductase of oxygenic
photosynthesis situated in the thylakoid membrane of cyanobacteria, algae and plants. It …

NAD+-reducing [NiFe] hydrogenases are valuable biocatalysts for H2-based energy
conversion and the regeneration of nucleotide cofactors. While most hydrogenases are …

Clostridioides difficile causes a serious diarrheal disease and is a common healthcare-
associated bacterial pathogen. Although it has a major impact on human health, the …

Evolution creates functional diversity of proteins, the essential building blocks of all
biological systems. However, studies of natural proteins sampled across the tree of life and …

The terms biomimetic and bioinspired are very relevant in the field of bioinorganic chemistry
and have been widely applied. Although they were defined by the International Organization …

Background Sulfate-reducing bacteria (SRB) are frequently encountered in anoxic-to-oxic
transition zones, where they are transiently exposed to microoxic or even oxic conditions on …
