INTERACTION BETWEEN THE LEFT-HANDED Z-DNA AND POLYAMINE:THE CRYSTAL STRUCTURE OF THE D(CG)3 AND N-(2-AMINOETHYL)-1,4-DIAMINOBUTANE COMPLEX
Overview
The DNA fragment d(CG)3 was co-crystallized with, N-(2-aminoethyl)-1,4-diaminobutane (PA(24], a chemically synthesized, polyamine. The complex crystal contained one polyamine, 3 magnesium, cations and one sodium cation per duplex of d(CG)3, and well diffracted, the X-ray intensities up to 1.0 A resolution. The d(CG)3 took a, left-handed Z-DNA conformation, and the PA(24) molecule electrostatically, interacted with the phosphate groups of the d(CG)3 duplex.
