Modeling the effect of copper availability on bacterial denitrification [PDF]
, 2013 When denitrifying bacteria such as Paracoccus denitrificans respire anaerobically they convert nitrate to dinitrogen gas via a pathway which includes the potent greenhouse gas, nitrous oxide (NO). The copper-dependent enzyme Nitrous Oxide reductase (Nos)

Intramolecular Electron Transfer in Nitrite Reductases [PDF]
ChemPhysChem, 2005 AbstractThe copper‐ and heme‐containing nitrite reductases (NiRs) are key enzymes in denitrification. Their subunits contain two distinct redox‐active metal centers, an electron‐accepting site and a nitrite‐reducing site, to carry out the single‐electron reduction of nitrite to nitic oxide. Catalytic cycles of both enzyme families employ intramolecular

Highly diverse nirK genes comprise two major clades that harbour ammonium-producing denitrifiers [PDF]
, 2016 Background: Copper dependent nitrite reductase, NirK, catalyses the key step in denitrification, i.e. nitrite reduction to nitric oxide. Distinct structural NirK classes and phylogenetic clades of NirK-type denitrifiers have previously been observed ...

Dissimilatory Nitrite and Nitric Oxide Reductases [PDF]
Chemical Reviews, 1996 The inorganic nitrogen cycle (Figure 1) consists of several linked biological processes and one abiological process, the reaction of N2 and O2 in lightning discharges and internal combustion engines to produce NOx and, ultimately, nitrate. All of the processes except nitrogen fixation involve reduction or oxidation of species containing N-O bonds of ...

Impact of mitochondria on nitrite metabolism in HL-1 cardiomyocytes
Frontiers in Physiology, 2013 Apart from ATP synthesis mitochondria have many other functions, one being nitrite reductase activity. NO released from nitrite has been shown to protect the heart from ischemia/reperfusion injury in a cGMP-dependent manner.

A haloarchaeal ferredoxin electron donor that plays an essential role in nitrate assimilation [PDF]
, 2011 In the absence of ammonium, many organisms, including the halophilic archaeon Haloferax volcanii DS2 (DM3757), may assimilate inorganic nitrogen from nitrate or nitrite, using a ferredoxin-dependent assimilatory NO3-/NO2- reductase pathway.

Inheritance of nitrite reductase and regulation of nitrate reductase, nitrite reductase, and glutamine synthetase isozymes. [PDF]
Plant Physiology, 1984 Banding patterns of nitrate reductase (NR), nitrite reductase (NiR), and glutamine synthetase (GS) from leaves of diploid barley (Hordeum vulgare), tetraploid wheat (Triticum durum), hexaploid wheat (Triticum aestivum), and tetraploid wild oats (Avena barbata) were compared following starch gel electrophoresis.

Characterization of denitrifying activity by the alphaproteobacterium, Sphingomonas wittichii RW1
Frontiers in Microbiology, 2014 Sphingomonas wittichii RW1 has no reported denitrifying activity yet encodes nitrite and nitric oxide reductases. The aims of this study were to determine conditions under which S.

Spectroelectrochemical Elucidation of the Kinetics of Two Closely Spaced Electron Transfers [PDF]
, 2012 The use of spectroelectrochemistry to facilitate the analysis of an EE mechanism was reported in this work. Using a set of spectra as a function of potential, the spectra of all three oxidation states were determined using evolving window factor analysis.

Biotransformation of explosives by the old yellow enzyme family of flavoproteins [PDF]
, 2004 Several independent studies of bacterial degradation of nitrate ester explosives have demonstrated the involvement of flavin-dependent oxidoreductases related to the old yellow enzyme (OYE) of yeast. Some of these enzymes also transform the nitroaromatic
