Glutamine Synthetase and Glutamine Synthetase‐Like Protein from Human Brain [PDF]

Journal of Neurochemistry, 2000
Abstract: Glutamine synthetase (GS; EC 6.3.1.2), a key enzyme ofglutamate metabolism, and another enzyme possessing highhydroxylamine‐L‐glutamine transferase activity comparable to that of GS andtermed GS‐like protein (GSLP) were purified from human brain concurrently.

Simvastatin overcomes the pPCK1‐pLDHA‐SPRINGlac axis‐mediated ferroptosis and chemo‐immunotherapy resistance in AKT‐hyperactivated intrahepatic cholangiocarcinoma

Cancer Communications, EarlyView.
Abstract Background Intrahepatic cholangiocarcinoma (ICC) is a challenging cancer with an increasing incidence. The Phase III TOPAZ‐1/KEYNOTE‐966 study demonstrated chemo‐immunotherapy (CIT) as a significant advancement, potentially replacing traditional chemotherapy for advanced biliary tract cancer.

Photorespiration: metabolic pathways and their role in stress protection [PDF]

, 2000
Photorespiration results from the oxygenase reaction catalysed by ribulose-1,5-bisphosphate carboxylase/ oxygenase. In this reaction glycollate-2-phosphate is produced and subsequently metabolized in the photorespiratory pathway to form the Calvin ...

Mammalian Tolerance to Amino Acid Heterochirality

ChemBioChem, Accepted Article.
Organisms use amino acids predominantly in l‐configuration. On the other hand, a series of studies show that a variety of d‐amino acids also occur in mammals and amino acid homochirality is not complete. Mammals de novo synthesize most amino acids with l‐configuration, but serine and aspartate are converted from l‐ to d‐configuration by endogenous ...

Glutamine Synthetase

Journal of Biological Chemistry, 1972
Glutamine synthetase (EC 6.3.1.2) was localized in the mitochondrial fractions of liver from three uricotelic species. These were chicken (Gallus domesticus), pigeon (Columba livia), and snake (Thamnophis elegans). In rat liver, glutamine synthetase is an extramitochondrial enzyme being mainly associated with microsomes during cellular fractionation ...

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Impaired Volume Regulation and Electrophysiology of Astrocytes In Situ in a Mouse Model for Megalencephalic Leukoencephalopathy With Subcortical Cysts

Glia, EarlyView.
Cell culture studies show disrupted astrocyte physiology in the leukodystrophy MLC. Are intact astrocytes similarly affected? This study on astrocytes in MLC mouse brain slices confirms and extends in vitro studies on altered astrocyte physiology. ABSTRACT Electrical signaling, driven by ion fluxes between intra‐ and extracellular compartments, is ...

Intrinsically disordered inhibitor of glutamine synthetase is a functional protein with random-coil-like pKa values [PDF]

, 2017
The sequential action of glutamine synthetase (GS) and glutamate synthase (GOGAT) in cyanobacteria allows the incorporation of ammonium into carbon skeletons. In the cyanobacterium Synechocystis sp.
