A typical helical thong is composed of a nonpolar carboxyl terminus that inserts into a hydrophobic compartment created by two adjoining subunits on the opposite, corresponding layer. Thirty-seven of the 77 residues of which the helical thong and hydrophobic pocket consist, are apolar and involved in the direct contact between the helical thong and pocket.

Outline
Helical thongs provide a significant amount of intersubunit stabilization to the quaternary structure of glutamine synthetase by binding together subunits from the two layers. A typical helical thong is composed of a nonpolar carboxyl terminus that inserts into a hydrophobic compartment created by two adjoining subunits on the opposite, corresponding layer. Thirty-seven of the 77 residues of which the helical thong and hydrophobic pocket consist, are apolar and involved in the direct contact between the helical thong and pocket. These residues contain an atypical abundance of praline and valine, 16% and 10%, respectively. This unusual amount may serve to enhance its rigidity and cohesion.
