Glutamine synthetase is composed of 10 .
Each subunit is composed predominantly of 12 and 12 , as well as a .
The beta sheets are arranged into two separate partial beta barrels, one of which encompasses the ligand complex.
The active site within the secondary structure can be called a "bifunnel," providing access to ATP and glutamate at opposing ends.[1]
The ligands present are Cl, Mn, Adenosine Diphosphate, and L-Methionine-S-Sulfoximine Phosphate.
