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 …

This paper reviews dissimilatory nitrate reduction to ammonium (DNRA) in soils-a newly
appreciated pathway of nitrogen (N) cycling in the terrestrial ecosystems. The reduction of …

Two decades ago, theoretical model calculations played a truly minor role in understanding
mechanisms of redox-active metalloenzymes. The methods available to treat transition …

Nitrate is a key node in the network of the assimilatory and respiratory nitrogen pathways. As
one of the 'fixed'forms of nitrogen, nitrate plays an essential role in both nature and industry …

Nitrite is one of the players in the broad nitrogen biogeochemical cycle. This nitrogen oxo-
anion is involved in key pathways crucial to life on Earth and to the planetary “recycling” of …

Ammonia oxidizing bacteria extract energy for growth from the oxidation of ammonia to
nitrite. Ammonia monooxygenase, which initiates ammonia oxidation, remains enigmatic …

Porphyrins and metalloporphyrins are the key pigments of life on earth as we know it,
because they include chlorophyll (a magnesium‐containing metalloporphyrin) and heme …

Nitrite is widely used by bacteria as an electron acceptor under anaerobic conditions. In
respiratory nitrite ammonification an electrochemical proton potential across the membrane …

Dissimilatory nitrate reduction to ammonium (DNRA) and denitrification are contrasting
microbial processes in the terrestrial nitrogen (N) cycle, in that the former promotes N …

Nitrogen (N) is one of the primary nutrients required to build biomass and is therefore in high
demand in aquatic ecosystems. Estuaries, however, are frequently inundated with high …
