Bacterial nitrate reductases: Molecular and biological aspects of nitrate reduction
(Elsevier Science Inc, 2006-05)
Nitrogen is a vital component in living organisms as it participates in the making of essential biomolecules such as proteins, nucleic acids, etc. In the biosphere, nitrogen cycles between the oxidation states +V and -III ...
Dissecting the role of NtrC and RpoN in the expression of assimilatory nitrate and nitrite reductases in Bradyrhizobium diazoefficiens
(Springer, 2016-12)
Bradyrhizobium diazoefficiens, the nitrogen-fixing endosymbiont of soybeans, is a model strain for studying rhizobial denitrification. This bacterium can also uses nitrate as the sole nitrogen (N) source during aerobic ...
EFFECT OF PHOTOSYNTHETIC INHIBITOR HERBICIDES ON NITRATE REDUCTASE ACTIVITY OF NON-TARGET SPECIESEFFECT OF PHOTOSYNTHETIC INHIBITOR HERBICIDES ON NITRATE REDUCTASE ACTIVITY OF NON-TARGET SPECIES
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1979)
EPR and redox properties of periplasmic nitrate reductase from Desulfovibrio desulfuricans ATCC 27774
(Springer, 2006-07)
Nitrate reductases are enzymes that catalyze the conversion of nitrate to nitrite. We report here electron paramagnetic resonance (EPR) studies in the periplasmic nitrate reductase isolated from the sulfate-reducing bacteria ...
Influence of metal ions and organic carbons on denitrification activity of the halotolerant bacterium, Paracoccus pantotrophus P16 a strain from shrimp pond
(Pontificia Universidad Católica de Valparaíso, 2009)
Lactobacillus delbrueckii subsp lactis strain CIDCA 133 inhibits nitrate reductase activity of Escherichia coli
(Elsevier Science, 2006-10)
The aim of the present work was to investigate the effect of strain CIDCA 133 on the nitrate reductase activity of a non-pathogenic Escherichia coli strain. Suspensions containing different ratios of the strains under study ...
Rapid and slow modulation of nitrate reductase activity in the red macroalga Gracilaria chilensis (Gracilariales, Rhodophyta): influence of different nitrogen sources
(SPRINGER, 2008)
Nitrate is one of the most important stimuli in nitrate reductase (NR) induction, while ammonium is usually an inhibitor. We evaluated the influence of nitrate, ammonium or urea as nitrogen sources on NR activity of the ...
