The octadeoxyribonucleotide d(CGCICICG) has been crystallized in space, group P(6)5(22) with unit cell dimensions of a = b = 31.0 A and c = 43.7, A, and X-ray diffraction data have been collected to 1.5-A resolution., Precession photographs and the self-Patterson function indicate that 12, base pairs of Z-conformation DNA stack along the c-axis, and the double, helices pack in a hexagonal array similar to that seen in other crystals, of Z-DNA. The structure has been solved by both Patterson deconvolution, and molecular replacement methods and refined in space group P(6)5 to an R, factor of 0.225 using 2503 unique reflections greater than 3.0 sigma (F)., Comparison of the molecules within the hexagonal lattice with highly, refined crystal structures of other Z-DNA reveals only minor, conformational differences, most notably in the pucker of the deoxyribose, of the purine residues. The DNA has multiple occupancy of C:I and C:G base, pairs, and C:I base pairs adopt a conformation similar to that of C:G base, pairs.
