Structure of the pure-spermine form of Z-DNA (magnesium free) at 1-A resolution. 
Biochemistry, 30, pp. 11388 - 11402, 1991.
X-RAY DIFFRACTION
P 21 21 21
a = 18.405 b = 30.768 c = 43.152 (Ångstroms)
α = 90.0 β = 90.0 γ = 90.0 (degrees)
The structure was refined using the PROLSQ program. The R value is 0.185 for 8183 reflections in the resolution range 0.0 to 1.0 Ångstroms with Fobs > 2.0 sigma(Fobs) and with I > 0.0 sigma(I)
