Evolution of copper-containing nitrite reductase
Copper-containing nitrite reductase (NiR) is a homotrimer of two cupredoxin domains and catalyzes the single electron reduction of NO2- to NO during dissimilatory denitrification. To investigate the evolution of NiR, methods of mutagenic library generation and high-throughput variant screening from …

Reactions of Nitroxyl and Nitrite in Blood
… a nitroxyl (HNO) and nitrite (NO<sub>2</sub><super>-</super>) donor, on plasma Hb oxidation, and on the vasoactivity of plasma Hb. Both HNO and nitrite are known to oxidize oxyHb to metHb. We hypothesized that AS could ameliorate hemolysis-associated pathology via its …

Nitrate and nitrite growth inhibition of Desulfovibrio strains
… can be inhibited by the chemicals nitrate and nitrite. Nitrate and nitrite are also present in heavy-metal contaminated environments and limit the growth of sulfate-reducing bacteria and their positive effects. In addition, nitrate and nitrite are often added to oil production processes to …

Nitrate- and Nitrite-Reductase Activities in Mycobacterium Avium A5
… medium (Nitrogen Test Medium) with glutamine, nitrite, nitrate, or ammonia as sole nitrogen source at a concentration of 2 mM at 370C aerobically. The strain grew well on all the nitrogen sources except nitrite. It grew slowly on nitrite with a generation time of 6 days and cultures were not …

Structure/function relationships of the copper proteins nitrite reductase and rusticyanin
… relationships of two copper proteins, nitrite reductase and rusticyanin using a combined approach of site-directed mutagenesis and X-ray crystallography. Dissimilatory nitrite reductase (NiR) catalyses the reduction of nitrite to nitric oxide (NO) as part of the key biological process …

The Impact of Nitrite on Aerobic Growth of Paracoccus denitrificans PD1222
The effect of nitrite stress induced in Paracoccus denitrificans PD1222 was examined using additions of sodium nitrite to an aerobic bacterial culture. Nitrite generates a strong stress response in P. denitrificans, causing growth inhibition. This is dependent on both the concentration of nitrite …

Dietary Intake and Bio-activation of Nitrite and Nitrate in Newborn Infants
<p>Nitrate and nitrite are commonly thought of as inert end products of nitric oxide (NO) oxidation, possibly carcinogenic food additives, or well-water contaminants. However, recent studies have shown that nitrate and nitrite play an important role in cardiovascular and gastrointestinal …

Kinetics reactions of Ammonium Nitrate-Sodium Nitrite Reaction and Ammonium Nitrate Emulsion Explosives
… emulsion explosive using ammonium nitrate-sodium nitrite reaction. This reaction produces N2 gas which is the sensitizer in emulsion explosives. The NH4NO3-NaNO2 gassing reaction produces N2 gas and so the reaction could be followed by the pressure increase in a closed reaction vessel. The …
