Protein attributes

Sequence length446 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Catalytic activity

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

Enzyme regulation

The activity of this enzyme is controlled by adenylation under conditions of abundant glutamine. The fully adenylated enzyme complex is inactive By similarity.

Subunit structure

Oligomer of 12 subunits arranged in the form of two hexagons By similarity.

Subcellular location

Cytoplasm.

Sequence similarities

Belongs to the glutamine synthetase family.
