Glutamine synthetase

Gene

GLUL

Organism
Sus scrofa (Pig)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Essential for proliferation of fetal skin fibroblasts. This enzyme has 2 functions: it catalyzes the production of glutamine and 4-aminobutanoate (gamma-aminobutyric acid, GABA), the latter in a pyridoxal phosphate-independent manner (By similarity).By similarity

Catalytic activityi

ATP + L-glutamate + NH3 = ADP + phosphate + L-glutamine.
L-glutamate = 4-aminobutanoate + CO2.

Cofactori
