Three-dimensional representation of (a) Con-T and (b) Con-G, indicating amino acids (left) and mesh structure (right). CGU = Gla: γ-carboxyglutamic acid. Conantokins adopt an α-helical solution structure in the presence of divalent cations in which charged carboxyl groups of the Gla residues are positioned along one face of the helix and hydrophobic residues are on the opposite face [83]. Figures were created with Pymol [82] (PDB 1ONT and 1ONU for Con-T and Con-G, respectively)
