Docking comparisons of Group A paraben ligands in human and rodent ERα-LBD receptors. (A) BuP human and mouse. (B) BuP human and rat. (C) iBuP human and mouse. (D) iBuP human and rat. Ligand colors: gray = human, magenta = mouse, orange = rat. Hydrogen bonds are represented as yellow dashes. Oxygen and nitrogen atoms are colored red and blue, respectively. Active site helix labels (H5, H11, and H12) are displayed in bold face. Hydrogen-bonding residues are displayed and labeled.
