Nitrate reductase from Pseudomonas aeruginosa

Biochimica et Biophysica Acta, 1961
Abstract Nitrate reductase has been purified 115-fold from actively denitrifying cells of Pseudomonas aeruginosa. The enzyme is DPNH dependent and contains FAD, cytochrome c and molybdenum as functional components. Sulphydryl groups are involved in binding the FAD to the apo-enzyme.

Nitrate reductase and cytochrome bnitrate reductase structural genes as parts of the nitrate reductase operon

Molecular and General Genetics MGG, 1981
The existence of a nitrate-reductase operon in the tryptophane region was deduced from the effects of prophage insertion in each of chlI and chlC genes and from transposition of the Mu-mediated host DNA fragments of F-prime. This operon appears to be polarized from chlC to chlI and the gene order in the region is trp -- chlI -- chlC -- purB.

Molecular evolution of nitrate reductase genes

Journal of Molecular Evolution, 1996
To understand the evolutionary mechanisms and relationships of nitrate reductases (NRs), the nucleotide sequences encoding 19 nitrate reductase (NR) genes from 16 species of fungi, algae, and higher plants were analyzed. The NR genes examined show substantial sequence similarity, particularly within functional domains, and large variations in GC ...

Nitrate reductase for nitrate analysis in water

Environmental Chemistry Letters, 2006
Nitrate analysis in water is one of the most frequently applied methods in environmental chemistry. Current methods for nitrate are generally based on toxic substances. Here, we show that a viable alternative method is to use the enzyme nitrate reductase.

The bacterial nitrate reductases: EPR studies on nitrate reductase A from Micrococcus denitrificans

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972
EPR studies on nitrate reductase indicate at 80 °K a signal at g=1.985 and g=2.045 attributable to Mo(V). At 15 °K a signal is observed at g=2.016 due to Fe(III) in an unknown symmetry. The reaction of nitrate reductase with nitrate, nitrite or azide results in changes of the Mo(V) signal.

Evolution of the soluble nitrate reductase: defining the monomeric periplasmic nitrate reductase subgroup

Biochemical Society Transactions, 2006
Bacterial nitrate reductases can be classified into at least three groups according to their localization and function, namely membrane-bound (NAR) or periplasmic (NAP) respiratory and cytoplasmic assimilatory (NAS) enzymes. Monomeric NASs are the simplest of the soluble nitrate reductases, although heterodimeric NASs exist, and a common structural ...

Blueberry Nitrate Reductase Activity

Journal of Small Fruit & Viticulture, 1996
ABSTRACT Nitrate Reductase activity (NRA) was detected in the blueberry cultivars (Vaccinium sp.)( ‘Bluecrop’ and Tifblue.' Shoots treated with KNO3 induced the highest level of NRA in leaves and stems of both cultivars. In ‘Bluecrop’ and Tifblue,1 the older leaves showed higher NRA compared to young leaves. Aluminum and sul-fate ions and various forms

[Induced activity of nitrate reductase by nitrate and cloning of nitrate reductase gene].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2010
Excessive nitrate accumulated in plants affects vegetable quality severely and excessive nitrate ingestion would do harm to human health. Assimilatory NADH: nitrate reductase (NR, EC 1.6.6.1), a complex Mo-pterin-, cytochrome b(557)- and FAD-containing protein, catalyzes the regulated and rate-limiting step in the utilization of inorganic nitrogen by ...
