Abstract

Guanine (G)-rich DNA sequences can adopt stable G-quadruplex structures by G-tetrad hydrogen-bonding and hydrophobic stacking. Recently, it has been shown that a DNA sequence forms an aptamer (termed 93del) and adopts a novel dimeric quadruplex folding topology in K⁺ solution. This aptamer exhibits anti-HIV1 integrase activity in the nanomolar range in vitro. A docking-based model of the 93del-integrase complex positions the DNA aptamer within a channel of the tetrameric integrase. This mutual fitting blocks several catalytic amino acid residues that are essential for integrase function, and accounts for the anti-HIV1 activity of the 93del aptamer.
