C-terminal domain interactions in the GIMFhelix mutant. Ribbon diagrams depicting the three-dimensional structures of GST subunits viewed perpendicular to the two-fold axis of symmetry for the dimer. The α9-helix and the tower region are highlighted in orange, β-strands are colored cyan, and GSH ligands are colored green. (A) Incorporation of the aromatic-aromatic interaction between Y217 in the α9-helix and F111 in the α4-turn-α5 tower region. (B) This interaction in not present in hGSTA1-1 (1PKW).
