Table 2.

Relative FRET efficiency (Erel) for the various conformations of 22AG as inferred from the comparison of the FRET and CD data at p = 1 bar and T = 25 °C.

Conformation Erel
Unfolded  ~ 0.33
Antiparallel  ~ 0.81
Parallel  ~ 0.47
Hybrid-1  ~ 0.88

The scheme at the top depicts the quadruplex structures adopted by the 22AG sequence: (A) the antiparallel, (B) the parallel, and (C) the hybrid-1 conformation. In the labeled sequences, the donor (FAM) is located at position 5′, and the acceptor (TAMRA) in position 3ʹ.
