Structure of the Mango-III aptamer. (a) Cartoon representation of the Mango-III aptamer in complex with TO1-Biotin (green sticks), highlighting the triplex and quadruplex nucleotides (warm orange-yellow colors), P2 helix (light blue), and binding pocket nucleotides (marine). (b) Front (top) and back (bottom) view of the P2 helical element. (c) Ligand binding pocket of the Mango-III-TO1-Biotin complex. Hydrogen bonds are represented with black dashes. (d) Ligand binding pocket of the Mango-III (A10U) mutant in complex with (Z)-TO1-Biotin.
