GLUL

(redirected from glutamine synthase)

GLUL

An intronless gene on chromosome 1q31 that encodes a glutamine synthetase, which catalyses the synthesis of glutamine from glutamate and ammonia. Glutamine is a key source of energy and is involved in cell proliferation, inhibition of apoptosis, and cell signalling. GLUL is expressed during early foetal stages, and plays an important role in controlling pH by removing ammonia from circulation.

Molecular pathology
GLUL mutations are associated with congenital glutamine deficiency.

In this biochemical process, the glutaminase enzyme catalyzes the glutamine hydrolysis and leads to the synthesis of ammonia and glutamate (Meister, 1980) or, the glutamine synthase enzyme catalyzes the conversion of glutamine from glutamate and ammonia in presence of ATP (Borges et al.
suggested that endophyte infected grasses represent greater activity of glutamine synthase, that is responsible for synthesis of glutamine in plant roots and thereby, the higher activity of L-glutaminase in the rhizosphere of E+ plants can be possibly attributed to higher concentration of the L-glutamine that is excreted into the rhizosphere and consequently induced higher levels of L-glutaminase activity.
In prokaryotes and eukaryotes, glutamine synthase plays an important role in the metabolism of nitrogen.
