Glutamate occupies a central position in amino acid metabolism in plants. The acidic amino
acid is formed by the action of glutamate synthase, utilizing glutamine and 2-oxoglutarate …

Glutamine synthetase assimilates ammonium into amino acids, thus it is a key enzyme for
nitrogen metabolism. The cytosolic isoenzymes of glutamine synthetase assimilate …

Amino Acid Metabolism, 3rd Edition covers all aspects of the biochemistry and nutritional
biochemistry of the amino acids. Starting with an overview of nitrogen fixation and the …

The amino acid phenylalanine (Phe) is a critical metabolic node that plays an essential role
in the interconnection between primary and secondary metabolism in plants. Phe is used as …

Abstract Glutamine synthetase (GS; EC 6.3. 1.2) is a key enzyme in nitrogen metabolism; it
catalyzes the critical incorporation of inorganic ammonium into glutamine. Two full-length …

Free amino acids, including theanine, glutamine and glutamate, contribute greatly to the
pleasant taste and multiple health benefits of tea. Amino acids in tea plants are mainly …

The majority if not all of the organic nitrogen in plants is derived from the assimilation of
ammonia into the amide position of glutamine by the enzyme glutamine synthetase (GS). A …

Low nitrogen availability is one of the main limiting factors for plant growth and development,
and high doses of N fertilizers are necessary to achieve high yields in agriculture. However …

We present the first cloning and study of glutamine synthetase (GS) genes in wheat (Triticum
aestivum L.). Based on sequence analysis, phylogenetic studies and mapping data, ten GS …

In a previous article, we highlighted the latest developments in the isolation and
characterisation of genes involved in the uptake of nitrogen from the soil, which might be …
