Crystal structure of tricyclo-DNA: an unusual compensatory change of two adjacent backbone torsion angles

Chem Commun (Camb). 2008 Feb 21:(7):883-5. doi: 10.1039/b716390h. Epub 2007 Dec 21.

Abstract

The crystal structure of a DNA duplex with tricyclo-DNA (tc-DNA) residues explains the increased RNA affinity of tc-DNA relative to DNA and tc-DNA's superior resistance to nucleases.
