Protein
Probable glutamine synthetase leaf isozyme
Gene
N/A
Organism
Pinus pinaster (Maritime pine)
Status
Reviewed - Annotation score: 2 out of 5 - Experimental evidence at protein 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.
