Figure 3. Triplex structure and interaction between choline ions and triplexes.

Figure 3

(a) The bases of the triplet of T–A*T are indicated by light blue, light green and pink. (b) The structure of Ts1 is depicted by the van der Waals model. First (5′-TTTTTTTCTTCT-3′), second (5′-AGAAGAAAAAAA-3′) and third (5′-TCTTCTTTTTTT-3′) strands are indicated by light blue, light green and pink, respectively. (c) Binding sites of choline ions around Ts1. Grey dots represent the appearance frequency of choline ions. Red and purple arrows indicate the highlighted binding site.
