Bacterial catalysis of nitrosation: involvement of the nar operon …
We have developed a rapid and sensitive fluorimetric method, based on the formation of a fluorescent product from nitrosation of 2,3-diaminonaphthalene, for measuring the ability of bacteria to catalyze nitrosation of amines.
A Novel Mechanism for Nitrosative Stress Tolerance Dependent …
2020年4月7日 · The discovery of NT suggests the presence of further anti-nitrosative stress systems in various microbes, such as pathogenic and model bacteria, fungi, and yeasts, including S. cerevisiae.
Biological Mechanisms of S-Nitrosothiol Formation and …
Such modifications occur through a process entitled S-nitrosylation (or nitrosation as it has also been termed), which satisfies all criteria as a mechanism for the regulation of cell physiology.
Nitrosamine Formation by Denitrifying and Non-denitrifying Bacteria …
Biochemical, microbiological and genetic studies were done to characterize the mechanism of bacterial formation of N-nitrosomorpholine (NMOR) from morpholine and nitrite at neutral pH.
Nitric oxide and nitrosative stress tolerance in bacteria
A 'systems biology' approach, integrating the methodologies of bacterial molecular genetics and physiology with post-genomic technologies, promises considerable advances in our understanding of bacterial NO tolerance mechanisms in pathogenesis.
Biochemical studies on the catalysis of nitrosation by bacteria
Biochemical and microbiological studies were conducted to characterize the mechanism of bacterial formation of N-nitrosomorpholine from morpholine and nitrite at neutral pH.
Anaerobic bacterial response to nitric oxide stress: Widespread ...
Synthesis of both the nitrate reductase, NarG, and NO detoxification enzymes were induced. This would provide an excellent source of bacteria to assess the level of protein −SH nitrosation in bacteria in a natural oxygen-limited environment.
Microbial responses to nitric oxide and nitrosative stress: growth ...
The study of bacterial responses to nitric oxide (NO), nitrosating agents, and other agents of nitrosative stress has a short history but has rapidly produced important insights into the interactions of these agents with model microbial systems as well as pathogenic species.
Nitric oxide as a source for bacterial triazole biosynthesis
2020年3月31日 · In this study, we revealed the involvement of a bacterial NOS in an enzymatic and non-enzymatic cascade leading to the formation of a rare 1,2,3-triazolopyrimidine scaffold.
Aerobic nitrous oxide production through N-nitrosating hybrid …
2014年1月9日 · Soil emissions are largely responsible for the increase of the potent greenhouse gas nitrous oxide (N2O) in the atmosphere and are generally attributed to the activity of nitrifying and ...
