Protein

Glutamine synthetase

Gene
glul
Organism
Xenopus laevis (African clawed frog)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

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. May play an important role in the early stages of vertebrate neural development.

Catalytic activityi

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

Cofactori

Biotin By similarity.
Magnesium or manganese By similarity.
