When faced with a shortage of oxygen, many bacterial species use nitrate to support
respiration via the process of denitrification. This takes place extensively in nitrogen-rich …

Under a shortage of oxygen, bacterial growth can be faced mainly by two ATP-generating
mechanisms:(i) by synthesis of specific high-affinity terminal oxidases that allow bacteria to …

Nitric oxide (NO) and nitrous oxide (N2O) are among nature's most powerful electron
acceptors. In recent years it became clear that microorganisms can take advantage of the …

The metallobiochemistry underlying the formation of the inorganic N–N-bond-containing
molecules nitrous oxide (N2O), dinitrogen (N2), and hydrazine (N2H4) is essential to the …

The structure of quinol-dependent nitric oxide reductase (qNOR) from G.
stearothermophilus, which catalyzes the reduction of NO to produce the major ozone …

The heme‑copper oxidoreductase (HCO) superfamily is a large superfamily of terminal
respiratory enzymes that are widely distributed across the three domains of life. The …

Recent advances in DNA sequencing technologies have provided unprecedented access
into the diversity of the microbial world. Herein we use the comparative genomic analysis of …

The crystal structures of bacterial nitric oxide reductases (NOR) from Pseudomonas
aeruginosa and Geobacillus stearothermophilus were reported. The structural …

Expression of two genes of unknown function, Staphylococcus aureus scdA and Neisseria
gonorrhoeae dnrN, is induced by exposure to oxidative or nitrosative stress. We show that …

A structural and functional model of bacterial nitric oxide reductase (NOR) has been
designed by introducing two glutamates (Glu) and three histidines (His) in sperm whale …
