Protein

Glutamine synthetase leaf isozyme, chloroplastic

Gene
N/A
Organism
Phaseolus vulgaris (Kidney bean) (French bean)
Status
Reviewed-Annotation score: Annotation score: 3 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.

Catalytic activityi

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