Protein

Glutamine synthetase leaf isozyme, chloroplastic

Gene
GS2, GLN
Organism
Medicago sativa (Alfalfa)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

The light-modulated chloroplast enzyme, encoded by a nuclear gene and expressed primarily in leaves, is responsible for the reassimilation of the ammonia generated by photorespiration By similarity.

Catalytic activityi

ATP + L-glutamate + NH3 = ADP + phosphate + L-glutamine.
