The NAD(P)H:flavin oxidoreductase from Escherichia coli. Evidence for a new mode of binding for reduced pyridine nucleotides [PDF]
The journal of biological chemistry, American Society for
Biochemistry and Molecular Biology, 1999, 274, pp.18252-60, 2015 The NAD(P)H:flavin oxidoreductase from Escherichia coli, named Fre, is a monomer of 26.2 kDa that catalyzes the reduction of free flavins using NADPH or NADH as electron donor. The enzyme does not contain any prosthetic group but accommodates both the reduced pyridine nucleotide and the flavin in a ternary complex prior to oxidoreduction.

Localization of the cytochrome cd1 and copper nitrite reductases in denitrifying bacteria
Journal of Bacteriology, 1990 The locations of cytochrome cd1 nitrite reductases in Pseudomonas aeruginosa and Pseudomonas fluorescens and copper nitrite reductases in Achromobacter cycloclastes and Achromobacter xylosoxidans were identified.

Water Research X, 2023 Simultaneous nitrification and denitrification (SND) is effective and energy-saving for wastewater treatment. As an inevitable intermediate product in the SND process, nitrite affects the efficiency of ammonia oxidation and the composition of nitrifiers.

Nitrogen metabolism in a grapevine in vitro system
OENO One, 2002 Ammonium, nitrate, nitrite, protein and individual and total amino acid contents were determined in grapevine (cv Sauvignon) cultured in vitro. The enzyme activities of nitrate and nitrite reductases, glutamine synthetase, glutamate synthetase and ...

Journal of the American Heart Association: Cardiovascular and Cerebrovascular DiseaseBackground Skeletal muscles are postulated to be a potent regulator of systemic nitric oxide homeostasis. In this study, we aimed to evaluate the impact of physical training on the heart and skeletal muscle nitric oxide bioavailability (judged on the ...

The stability of 3 transmembrane and 4 transmembrane human vitamin K epoxide reductase models [PDF]
, 2016 3 transmembrane and 4 transmembrane helices models are suggested for the human vitamin K epoxide reductase (VKOR). In this study, we investigate the stability of the human 3 transmembrane/4 transmembrane VKOR models employing a coarse-grained normal mode analysis and molecular dynamics simulation.

Molecular dynamics simulation of the order-disorder phase transition in solid NaNO$_2$ [PDF]
Physical Review B 68, 174106 (2003), 2003 We present molecular dynamics simulations of solid NaNO$_2$ using pair potentials with the rigid-ion model. The crystal potential surface is calculated by using an \emph{a priori} method which integrates the \emph{ab initio} calculations with the Gordon-Kim electron gas theory.

The reaction of Pseudomonas nitrite reductase and nitrite. A stopped-flow and EPR study. [PDF]
Journal of Biological Chemistry, 1990 The reaction between reduced Pseudomonas nitrite reductase and nitrite has been studied by stopped-flow and rapid-freezing EPR spectroscopy. The interpretation of the kinetics at pH 8.0 is consistent with the following reaction mechanism (where k1 and k3 much greater than k2).

Plants, 2020 Although the nitrate assimilation into amino acids in photosynthetic leaf tissues is active under the light, the studies during 1950s and 1970s in the dark nitrate assimilation provided fragmental and variable activities, and the mechanism of reductant ...
