In the brain protein fraction no L-glutamine hydrolysis is found without phosphate.

phosphate
-
structure-based phosphate activation mechanism of GAC and GLS1/KGA, introducing the tetramerization-induced lifting of a gating loop essential for the phosphate-dependent activation process, overview. Phosphate binds inside the catalytic pocket rather than at the oligomerization interface. Phosphate also mediates substrate entry by competing with glutamate. GLS1/KGA is as effective as GLS2/LGA, but presents an eightfold gain in efficiency at 50 mM phosphate, with kcat-app/Km-app of 0.4 mM/s and 17.6 mM/s, respectively. One ion bound per monomer, buried inside the highly positive active site where it makes polar contacts with Ser291, Asn340 and Tyr471, and two water molecules
