Nitric oxide (NO) is an important signaling molecule that is involved in a wide range of
physiological and pathological events in biology. Metal coordination chemistry, especially …

The nitrogen cycle is one of the most important biogeochemical cycles on Earth because
nitrogen is an essential nutrient for all life forms. To supplement natural nitrogen fixation …

Nitric oxide reductase (NOR) is an iron-containing enzyme that catalyzes the reduction of
nitric oxide (NO) to generate a major greenhouse gas, nitrous oxide (N2O). Here, we report …

As an alternative to photosynthesis or aerobic respiration, many microbial species can
respire anaerobically to gain energy for cell growth. 1-4 A variety of bacteria employ a …

One of the hallmarks of bacterial physiology is the ability to use a wide variety of substrates
as oxidants or terminal oxidants for respiration. Because of its high redox potential and …

The investigation of respiratory N-oxide reduction as part of a biogeochemical process
sustained by prokaryotes has roots over a century ago and has laid the groundwork for …

Enzymatic reactions involving inorganic nitrogen species provide a rich variety of systems
with which to study biological chemistry. In many cases, catalysis involves redox chemistry …

Nitric oxide reductases (NORs) that are found in bacteria belong to the large enzyme family
which includes cytochrome oxidases. Two types of bacterial NORs have been characterised …

High-spin non-heme iron–nitrosyls are of direct interest to both the chemical and biological
communities as these species exhibit interesting chemical properties and act as direct …

This review summarizes recent developments in the investigation of the electronic
structures, spectroscopic properties, and reactivities of ferrous and ferric heme-nitrosyls and …
