General annotation (Comments)

Function

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 activity

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

Subunit structure

Homooctamer By similarity.

Subcellular location

Plastidchloroplast By similarity.

Miscellaneous

On the 2D-gel the determined pI of this protein is: 5.7, its MW is: 42 kDa.

Sequence similarities

Belongs to the glutamine synthetase family.
