Glutamine synthetase nodule isozyme

Gene

GS1

Organism
Pisum sativum (Garden pea)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Miscellaneous

In pea there are distinct isozymes in leaves, roots and nodules.
Irreversibly inhibited by the herbicide L-phosphinothricin (PPT).
This root isozyme is responsible for the assimilation of ammonia fixed by bacteroids.

Catalytic activityi

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