Antioxidants have been widely studied in the fields of biology, medicine, food, and nutrition
sciences. There has been extensive work on developing assays for foods and biological …

Nitric oxide (NO) is a small free radical with critical signaling roles in physiology and
pathophysiology. The generation of sufficient NO levels to regulate the resistance of the …

Nitric oxide (NO) is a poison, and organisms employ diverse systems to protect against its
harmful effects. InEscherichia coli, ygaA encodes a transcription regulator (b2709) …

The major pathway for nitric oxide scavenging in red cells involves the direct reaction of the
gas with HbO2 to form nitrate and the ferric form of the protein, metHb. Because both atoms …

Microbial flavohemoglobins (flavoHbs) and hemoglobins (Hbs) show large NO
dioxygenation rate constants ranging from 745 to 2900 μM− 1s− 1 suggesting a primal NO …

Sulfur-oxidizing epsilonproteobacteria are common in a variety of sulfidogenic
environments. These autotrophic and mixotrophic sulfur-oxidizing bacteria are believed to …

Ralstonia eutropha is a strictly respiratory facultative lithoautotrophic β-proteobacterium. In
the absence of organic substrates, H2 and CO2 are used as sole sources of energy and …

Nitric oxide (NO) is an intermediate of the respiratory pathway known as denitrification, and
is a by-product of anaerobic nitrite respiration in the enteric Bacteria. Pathogens are also …

Microarray studies of the Escherichia coli response to nitric oxide and nitrosative stress have
suggested that additional transcriptional regulators of this response remain to be …
