Docking clusters and TEA-Tyr (Tetraethylammonium-Tyrosine) (99 and 205) distances: (A,C,E,G) cluster of TEA poses (in green color) obtained by docking analysis for 2loop2, 2loop2/A99, 2loop2/A205 and 2loop2/A99/A205 channels, respectively. In red are shown the residues forming the binding site of TEA near to the selectivity filter (SF). In yellow color, K+ ions are depicted and water molecules are represented in red and white, placed in the SF. The superscript letter implies the monomer to which it belongs. (B) shows the distances between the 1st best poses and the tyrosine residues, respectively. Similarly, the distances between the 1st best poses and the tyrosine residues 2loop2/A99, 2loop2/A205 and 2loop2/A99/A205 mutant channels are shown in (D,F,H), respectively.
