The highly symmetric centre of the homotetramer. The side chains of the four Ser117 residues form a barrier between the two hormone binding sites. The 2FoFc neutron map (at 1.2 r.m.s.) shows clearly the different orientation of the γ-deuterium atoms of serine residues in chains A and B, and the presence of only one water molecule.
