(a) The electrostatic surfaces of the hexamer of IGlu, 4INS and 4EY9 side view (left) and top view from the three fold axis (right). (b) D3Lys and B22Arg (symmetry) are both positively charged and in only 5.07 Å distance which contributes to the electrostatic repulsion. Figures created using COOT v0.8.9.1.
