We have determined the structure of the dodecamer duplex d(CGCCCGCGGGCG)2. A careful use of the molecular replacement programme AMoRe has been essential in order to solve the structure. This dodecamer shows a unique conformation, quite different from all the previously studied oligonucleotide duplexes: the central octamer has an A conformation, but with a sharp 65 degrees kink in the centre; the terminal base-steps have a B-like conformation; the major groove is completely closed in the centre, a hollow molecule is thus found. The results obtained confirm the high degree of variability of DNA structure. A new type of kink and an intermediate A/B double-helical conformation have been found. Such intermediate conformation differs from those described in DNA polymerase complexes.
