Eucalyptus ESTs corresponding to the enzyme glutamine synthetase and the protein D1, sites of action of herbicides that cause oxidative stress

open access: yesGenetics and Molecular Biology, 2005
This work was aimed at locating Eucalyptus ESTs corresponding to the GS enzyme (Glutamine Synthetase, EC = 6.3.1.2) and to the D1 protein, which are directly related to resistance to herbicides that promote oxidative stress.

Glutamine Phosphoribosylpyrophosphate Amidotransferase-independent Phosphoribosyl Amine Synthesis from Ribose 5-Phosphate and Glutamine or Asparagine [PDF]

open access: yes, 2007
Phosphoribosylamine (PRA) is the first intermediate in the common pathway to purines and thiamine and is generated in bacteria by glutamine phosphoribosylpyrophosphate (PRPP) amidotransferase (EC 2.4.2.14) from PRPP and glutamine.

Two cytosolic glutamine synthetase isoforms play specific roles for seed germination and seed yield structure in Arabidopsis

open access: yesJournal of Experimental Botany, 2014
Summary Knockout of glutamine synthetase isogene Gln1;2 reduces nitrogen remobilization and the number and size of siliques and seeds in Arabidopsis. Gln1;1 affects the response of primary root development to exogenous nitrogen.

Stomatal NH3 compensation point and its metabolic regulation in senescence phenotypes of Nicotiana tabacum

open access: yesBiologia Plantarum, 2012
We compared stomatal ammonia compensation point (χs) and its metabolic regulation in tobacco (Nicotiana tabacum) leaves of a quick-leaf-senescence phenotype ZY90 and a slow-leaf-senescence phenotype NC89. Compared with NC89, ZY90 had significantly higher

The role of glutamine synthetase expression and cystine/glutamate transporter (SLC7A11, xCT) in epilepsy pathogenesis of patients with supratentorial brain gliomas

open access: yesЭпилепсия и пароксизмальные состояния, 2022
Background. Epileptic seizures represent one of the leading clinical manifestations of glial brain tumors that develop on average in 51% of cases. In gliomas, epileptogenesis is quite complex and multifactorial.Objective: to study a role of the expressed

Macrophage-derived glutamine boosts satellite cells and muscle regeneration

open access: yesNature, 2020
Muscle regeneration is sustained by infiltrating macrophages and the consequent activation of satellite cells 1 – 4 . Macrophages and satellite cells communicate in different ways 1 – 5 , but their metabolic interplay has not been investigated.
