Molecular recognition of a three-way DNA junction by a metallosupramolecular helicate

(Figure Presented) Three point turn: A metallosupramolecular helicate with trigonal-antiprismatic geometry fits perfectly into the central hydrophobic cavity of a three-way DNA junction allowing a new mode of DNA recognition. © 2006 Wiley-VCH Verlag GmbH & Co.
