Protein

Glutamine synthetase, chloroplastic

Gene

GLN2

Organism
Zea mays (Maize)
Status
Reviewed - Annotation score: 5 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.

Catalytic activityi

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