WebGlutamine synthetase (GS), a Mn-dependent enzyme, plays an important role in metabolizing nitrogen by catalyzing the reaction of condensation of glutamate and … WebGlutamate synthase. Glutamate synthase (also known as Glutamine oxoglutarate aminotransferase) is an enzyme and frequently abbreviated as GOGAT. This enzyme manufactures glutamate from glutamine and α-ketoglutarate, and thus along with glutamine synthetase (abbreviated GS) plays a central role in the regulation of nitrogen assimilation …
WebGlutamine nutrition in the cell regulates the mTORC1 signaling pathway, which signals cell growth and cell cycle progression. Glutamine is also necessary for glutathione production within a cell to maintain redox homeostasis (Altman et al., 2016; Wise and Thompson, 2010). WebThe GS/GOGAT pathway is a two-step process: first, the glutamine synthetase (GS) generates glutamine from glutamate and ammonium; next, the glutamine oxoglutarate aminotransferase /glutamate synthase (GOGAT) forms two molecules of glutamate from glutamine and α-ketoglutarate. The GS/GOGAT pathway is the most active ammonium …
