The functional nitrite reductase activity of the heme-globins.
Hemoglobin and myoglobin are among the most extensively studied proteins, and nitrite is one of the most studied small molecules. Recently, multiple physiologic studies have surprisingly revealed that nitrite represents a biologic reservoir of NO that can regulate hypoxic vasodilation, cellular respiration, and signaling. These studies suggest a vital role for deoxyhemoglobin- and deoxymyoglobi...
متن کاملDiversity of the nitrite reductase gene nirS in the sediment of a free-water surface constructed wetland.
The diversity of the nitrite reductase gene nirS was studied in the bulk sediment of a free-water surface constructed wetland (FWS-CW) located next to the Empuriabrava wastewater treatment plant (WWTP), in Castelló d'Empúries (Girona, NE Spain). The study period extended from the inception of the treatment wetland, in June 1998, until March 1999 and comprised periods of relatively high nitrate ...
متن کاملCharacterization of bacterial cytochrome cd(1)-nitrite reductase as one enzyme responsible for catalysis of nitrosation of secondary amines.
Bacterial formation of carcinogenic N-nitroso compounds may play a role in the etiology of human cancer. Biochemical and immunological studies in denitrifying bacteria (Pseudomonas aeruginosa) strongly support the identification of cytochrome cd(1)-nitrite reductase as the enzyme responsible for the catalysis of nitrosation through the production of nitric oxide or NO(+)-like species. Interesti...
متن کاملDiversity of nitrite reductase genes (nirS) in the denitrifying water column of the coastal Arabian Sea
Denitrification often occurs in the water column, underlying zones of intense productivity and decomposition in upwelling regions. In the denitrifying zone off the southwest coast of India, high concentrations of nitrite (>15 μM) and nitrous oxide (>500 nM) have been reported near the sediment-water interface (<80 m). We investigated the chemical and molecular indicators of denitrification alon...
متن کاملDiversity of nitrite reductase (nirK and nirS) gene fragments in forested upland and wetland soils.
The genetic heterogeneity of nitrite reductase gene (nirK and nirS) fragments from denitrifying prokaryotes in forested upland and marsh soil was investigated using molecular methods. nirK gene fragments could be amplified from both soils, whereas nirS gene fragments could be amplified only from the marsh soil. PCR products were cloned and screened by restriction fragment length polymorphism (R...
