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 …

Redox reactions play important roles in almost all biological processes, including
photosynthesis and respiration, which are two essential energy processes that sustain all life …

The respiration of oxygen is fundamental to the life of higher animals and plants. The basic
respiratory process in the mitochondria of these organisms involves the donation of …

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 …

Cytochrome cbb3 oxidases are found almost exclusively in Proteobacteria, and represent a
distinctive class of proton-pumping respiratory heme-copper oxidases (HCO) that lack many …

Isotopomer ratios of N2O, which include intramolecular 15N-site preference in addition to
conventional isotope ratios for N and O in NNO (we designate Nα and Nβ for the center 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 …

Denitrification, or dissimilative nitrate reduction, is an anaerobic process used by some
bacteria for energy generation. This process is important in many aspects, but its …

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 …
