title: Quadruplex DNA crystal structures and drug design.
abstract: Crystallographic studies of G-quadruplex nucleic acids have resulted in a small group of structures to date. Their morphological and detailed conformational features are described here, emphasizing the stability of the G-tetrad core and the flexibility of loops, especially upon ligand binding. Implications for drug design are discussed, in the context of the druggability of both telomeric and non-telomeric quadruplex DNAs.
