THE CRYSTAL AND MOLECULAR STRUCTURE OF A NEW Z-DNA CRYSTAL FORM: D[CGT(2-NH2-A) CG] AND ITS PLATINATED DERIVATIVE
Overview
The three-dimensional structure of d[CGTA'CG], where A' = [2-NH2-A], was, determined to atomic (1.35 A) resolution by single isomorphous, replacement. The d[CGTA'CG] hexamer crystallizes in space group P3221, and, is not isomorphous with other DNA hexanucleotides. Despite completely, different crystal packing, the essential characteristics of the Z-DNA, conformation are maintained. The structure was determined by single, isomorphous replacement using a triammine platinum fragment. Thus, this, study also demonstrates, for the first time, the feasibility of the use of, this reagent for the direct phasing of DNA crystal structures.
