Preparación de genotecas de ADNc de Plasmodium falciparum para la búsqueda de los genes de proteínas de unión a calmodulina, GOGAT y Pfmyo A.

Biomédica: revista del Instituto Nacional de Salud, 2002
Se construyó una genoteca de ADNc representativa de los estadios asexuales de Plasmodium falciparum, en el vector lZipLox. Esta genoteca (de la cepa colombiana FCB2) y otra genoteca construida en lZAP II (de la cepa Dd2), se rastrearon en busca de genes ...

The roles of glutamate dehydrogenase, glutamine synthetase and three forms of glutamate synthase on nitrogen assimilation in various organs of Pisum arvense L.

Acta Societatis Botanicorum Poloniae, 2014
The activities of GDH, GS and three forms of GOGAT (NADH, NADPH or ferredoxin-dependent) were studied in the leaves, stems and roots of the Pisum arvense.

Allelic Variants of Glutamine Synthetase and Glutamate Synthase Genes in a Collection of Durum Wheat and Association with Grain Protein Content

Diversity, 2017
Wheat is one of the most important crops grown worldwide. Despite the fact that it accounts for only 5% of the global wheat production, durum wheat (Triticum turgidum L. subsp. durum) is a commercially important tetraploid wheat species, which originated

Light-Independent Nitrogen Assimilation in Plant Leaves: Nitrate Incorporation into Glutamine, Glutamate, Aspartate, and Asparagine Traced by ¹⁵N

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 ...

Glutamate Synthase Activity in Symbiotic Cyanobacteria [PDF]

Microbiology, 1981
Glutamate synthase (GOGAT) activities of the symbiotic cyanobacteria of the lichens Peltigera canina and Peltigera aphthosa and of the water fern Azolla caroliniana have been determined and, like glutamine synthetase (GS) activity, found to be substantially reduced compared with the activities found in the free-living cyanobacteria. A similar reduction

Effect of a mix of oligogalacturonides on symbiotic nitrogen fixation in common bean

Agronomía Colombiana, 2021
The objective of this study was to evaluate the effect of a mix of pectic oligosaccharides in the common bean-rhizobia symbiosis. Cuba Cueto-25-9-N bean seeds were inoculated with Rhizobium tropici CIAT 899 and treated with a mix of oligogalacturonides,

The impact of RNA binding proteins and the associated long non-coding RNAs in the TCA cycle on cancer pathogenesis

RNA Biology, 2023
The tricarboxylic acid (TCA) cycle is a central route for generating cellular energy and precursors for biosynthetic pathways. Emerging evidences have shown that the aberrations of metabolic enzymes which affect the integrity of TCA cycle are implicated ...

NtANTL2 overexpression regulates starch-related and nitrogen metabolism in tobacco plants

BMC Plant Biology
The function of the aromatic and neutral amino acid transporter gene ANT1-like (NtANTL2) was investigated. NtANTL2-3 over-expressor plants displayed greater tolerance to high nitrogen application compared to WT plants, characterized by better growth.

Effect of brassinosteroids on ammonium uptake via regulation of ammonium transporter and N-metabolism genes in Arabidopsis

Biologia Plantarum, 2016
Several studies have been performed to elucidate the role of brassinosteroids (BRs) in plant growth and development. However, information on the role of BR signaling in nutrient uptake is limited.

Active Subunits of Escherichia coli Glutamate Synthase [PDF]

Journal of Bacteriology, 1976
The large and small subunits of Escherichia coli glutamate synthase were isolated. The small subunit catalyzes the NH 3 -dependent synthesis of glutamate. The large subunit exhibits glutaminase activity.
