WebGlutamine synthetase (E.C. 6.3.1.2), referred to for brevity as GS, catalyzes the amidation of glutamate to glutamine. Glutamine is of major importance in a variety of biosynthetic pathways including the synthesis of proteins, mucopolysaccharides, and nucleic acids (Meister, 1974 ). GS is present throughout the nervous system of higher ... WebFor glutamate-related metabolism in astrocytes (Fig. 7), it can be converted to glutamine by the glutamine synthetase, and also be catalyzed by glutamate dehydrogenase to produce α-ketoglutarate which participates in the TCA cycle and ultimately produces ATP [52]. GS activity is associated with the regulation of adenylation and the involvement ...
