PubMed Abstract: In vitro selection has identified DNA aptamers that target cofactors, amino acids, peptides and proteins. Structure determination of such ligand-DNA aptamer complexes should elucidate the details of adaptive DNA structural transitions, binding-pocket architectures and ligand recognition. We have determined the solution structure of the complex of a DNA aptamer containing a guanine-rich 18-residue hairpin loop that binds L-argininamide with approximately 100 microM affinity.
