The ligand-binding domain of each unit involves <scene name='Sandbox_Reserved_490/Lbd_active_residues/1'>key residues</scene> from helices 7, 8, and 9 in the binding pocket. Most of the residues are hydrophobic, to interact with the hydrophobic portions of the estrogen steroid. The Glu-353 and His-524 hydrogen bond directly with the hydroxyl groups on the estrogen ligand.[http://www.ncbi.nlm.nih.gov/pmc/articles/PMC27574/]
