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)
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 ...
Substrate binding to a nitrite reductase induces a spin transition
(American Chemical Society, 2010-04)
The multiheme enzyme nitrite reductase catalyzes a 6-electron reduction of nitrite to ammonia. The reaction is initiated by substrate binding to the free axial position of the high spin penta-coordinated heme active site. ...
Overexpression, purification, and biochemical and spectroscopic characterization of copper-containing nitrite reductase from Sinorhizobium meliloti 2011. Study of the interaction of the catalytic copper center with nitrite and NO
(Elsevier Science Inc., 2012-09)
The entire nirK gene coding for a putative copper-nitrite reductase (Nir) from Sinorhizobium meliloti 2011 (Sm) was cloned and overexpressed heterologously in Escherichia coli for the first time. The spectroscopic and ...
Heterologous production and functional characterization of: Bradyrhizobium japonicum copper-containing nitrite reductase and its physiological redox partner cytochrome c 550
(Royal Society of Chemistry, 2020-11)
Two domain copper-nitrite reductases (NirK) contain two types of copper centers, one electron transfer (ET) center of type 1 (T1) and a catalytic site of type 2 (T2). NirK activity is pH-dependent, which has been suggested ...
Nitrite as the major source of nitric oxide production by Arabidopsis thaliana in response to Pseudomonas syringae
(Elsevier Science BvAmsterdamHolanda, 2005)
A three-domain copper-nitrite reductase with a unique sensing loop
(International Union of Crystallography, 2019-01)
Dissimilatory nitrite reductases are key enzymes in the denitrification pathway, reducing nitrite and leading to the production of gaseous products (NO, N2O and N2). The reaction is catalysed either by a Cu-containing ...
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 ...
