Ferrostatin-1 protects HT-22 cells from oxidative toxicity

Neural Regeneration Research, 2020
Ferroptosis is a type of programmed cell death dependent on iron. It is different from other forms of cell death such as apoptosis, classic necrosis and autophagy. Ferroptosis is involved in many neurodegenerative diseases.

Inducible nitric oxide inhibitors block NMDA antagonist-stimulated motoric behaviors and medial prefrontal cortical glutamate efflux

Frontiers in Pharmacology, 2015
Nitric oxide (NO) plays a critical role in the motoric and glutamate releasing action of N-methyl-D-aspartate (NMDA)-antagonist stimulants. Earlier studies utilized neuronal nitric oxide synthase inhibitors (nNOS) for studying the neurobehavioral effects

Comparative metabolic profiling of the lipid-producing green microalga Chlorella reveals that nitrogen and carbon metabolic pathways contribute to lipid metabolism

Biotechnology for Biofuels, 2017
Microalgae are a promising feedstock for biofuel production. Microalgal metabolic pathways are heavily influenced by environmental factors. For instance, lipid metabolism can be induced by nitrogen-limiting conditions.

Crystal structure of the N-acetyltransferase domain of human N-acetyl-L-glutamate synthase in complex with N-acetyl-L-glutamate provides insights into its catalytic and regulatory mechanisms. [PDF]

PLoS ONE, 2013
N-acetylglutamate synthase (NAGS) catalyzes the conversion of AcCoA and L-glutamate to CoA and N-acetyl-L-glutamate (NAG), an obligate cofactor for carbamyl phosphate synthetase I (CPSI) in the urea cycle.

The occurrence of glutamate synthase in algae

Biochemical and Biophysical Research Communications, 1975
Abstract The presence of glutamate synthase in the green algae Chlorella fusca var. vacuolata has been demonstrated using a whole cell assay as well as cell free extracts. The assay is complicated by the presence of glutamine (amino): α-oxoglutarate transaminase, but this enzyme can be inhibited by amino oxyacetate. The rates of glutamate

The activity of NADH-, NADPH- and Fd-dependent glutamate synthase in the plastids and cytosol of Pisum arvense L. root cells

Acta Societatis Botanicorum Poloniae, 2014
Three forms of glutamate synthase (NADH-GOGAT, NADPH-GOGAT and Fd-(ferredoxin) GOGAT) were found in the plastids and cytosol of Pisum arvense root cells.

Salmonella typhimurium Mutants with Altered Glutamate Dehydrogenase and Glutamate Synthase Activities [PDF]

Journal of Bacteriology, 1980
Although glutamate is a key compound in nitrogen metabolism, little is known about the function or regulation of its two biosynthetic enzymes, glutamate dehydrogenase and glutamate synthase. To begin the characterization of glutamate formation in Salmonella typhimurium , we isolated mutants having altered glutamate ...

A carbon-nitrogen negative feedback loop underlies the repeated evolution of cnidarian–Symbiodiniaceae symbioses

Nature Communications, 2023
Symbiotic associations with Symbiodiniaceae have evolved independently across a diverse range of cnidarian taxa including reef-building corals, sea anemones, and jellyfish, yet the molecular mechanisms underlying their regulation and repeated evolution ...

Importance of Glutamate Synthase in Glutamate Synthesis by Soybean Cell Suspension Cultures [PDF]

Plant Physiology, 1979
The specific activities of glutamate synthase|EC 2.6.1.53, l-glutamine: alpha-ketoglutarate amino transferase (NADPH-oxidising)| and glutamine synthetase|EC 6.3.1.2, l-glutamate: ammonia ligase (ADP-forming)| extracted from soybean (Glycine max L.) cells grown in modified B5 medium were found to vary significantly in response to variations in the ...

Sulfur and Calcium Simultaneously Regulate Photosynthetic Performance and Nitrogen Metabolism Status in As-Challenged Brassica juncea L. Seedlings

Frontiers in Plant Science, 2018
In the present study, the role of sulfur (K2SO4: S; 60 mg S kg-1 sand) and/or calcium (CaCl2: Ca; 250 mg Ca kg-1 sand) applied alone as well as in combination on growth, photosynthetic performance, indices of chlorophyll a fluorescence, nitrogen ...
