Theanine is similar to the brain active substances glutamine and glutamic acid in chemical structure, and it is the main component of the tea to generate saliva and moisten the sweet. Therefore, it is commonly used as a tea improver. At the same time, theanine...

(1), the enzyme activity was measured at concentrations ranging from (2.0–20.0 mM) of L-asparagine, L-glutamine, aspartic acid, and glutamic acid as substrates to find the Michaelis-Menten constant (Km) and maximum reaction velocity (Vmax) values of the pure asparaginase. 1v=1Vmax+KmVmax...
Fetal Bovine serum, DMEM, RPMI-1640, HEPES buffer solution, L-glutamine, gentamycin and 0.25% Trypsin-EDTA were purchased from Lonza. Topoisomerase I inhibitory assay To measure topo I levels, Human TOP1 (DNA topoisomerase 1) ELISA kits (Catalog No.: MBS763851) were used. Briefly, the ...
Amino acid availability is monitored by animals to adapt to their nutritional environment. Beyond gustatory receptors and systemic amino acid sensors, enteroendocrine cells (EECs) are believed to directly percept dietary amino acids and secrete regulator
(Pisum sativumL.) with chitosan under cadmium stress led to a decrease in the concentrations of phosphorus, potassium, and calcium. The notable impact of chitosan on plant development may be attributed to the enhanced activity of nitrogen metabolism enzymes, including glutamine synthase, reductase, ...
We find GO terms for glutamate synthases and glutamine metabolic processes abundant already 30 hai, which could be upregulated to support the GABA-shunt. An alternative explanation suggests an indirect role in the production of secondary metabolites: Glutamine synthase have been shown upregulated in ...

drought-stressed plants, e.g. inMedicago sativa(Girousse et al.1996) while glutamate and glutamine are the most abundant amino acids in the phloem of oilseed rape when it is well watered (Lohaus and Moellers2000). Thus, proline is closely connected to the glutamate–glutamine metabolism ...
The cells were cultured in RPMI-1640 medium supplemented with 10% heat-inactivated fetal bovine serum (FBS), 2 mM L-glutamine, 1 mM Na-pyruvate, 100 mM HEPES. The MRC-5 (ATCC CCL-171) human embryonic lung fibroblast cell line and the hormone-responsive breast cancer cell line MCF-7 (...
