New lego pieces: The formation of a glucose–nucleobase pseudo base pair is proposed as a new type of biomolecular interaction. When formed within a DNA double helix the high-resolution structure shows only a minor distortion. These DNA duplexes are less stable than natural ones, but glucose shows preference for binding purine nucleobases. Moreover, quantum chemical calculations indicate that glucose–purine pairs are as stable as a natural T–A pair..
