Protein

Glutamine synthetase leaf isozyme, chloroplastic

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

Miscellaneous

There are at least four isozymes of this enzyme in P.vulgaris.
Irreversibly inhibited by the herbicide L-phosphinothricin (PPT).

Catalytic activityi

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