CRYSTAL AND MOLECULAR STRUCTURE OF A DNA FRAGMENT CONTAINING A 2-AMINO ADENINE MODIFICATION: THE RELATIONSHIP BETWEEN CONFORMATION, PACKING, AND HYDRATION IN Z-DNA HEXAMERS


Overview

The crystal and molecular structure of d(CGUA'CG)2 (where A' is 2-aminoadenine) has been determined and refined to an R factor of 13.8% for data 8.0-1.3 A. The structure is very similar to the original Z-DNA structures with the sequence d(CGCGCG)2 [Gessner, R. V., Frederick, C. A., Quigley, G. J., Rich, A., & Wang, A. H.-J. (1989) J. Biol. Chem. 264, 7921] and shows that the substitution of 2-aminoadenine-uracil base pairs in the two central steps is consistent with Z-DNA formation. In addition, we show how waters mediating intermolecular interactions may help to explain the ZI-ZII conformational pattern found in many Z-DNA structures.
