Crystal structure at 1.5-A resolution of d(CGCICICG), an octanucleotide containing inosine, and its comparison with d(CGCG) and d(CGCGCG) structures. 
Biochemistry, 31, pp. 1541 - 1550, 1992.

Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 65

Cell Constants:

a = 31.0   b = 31.0   c = 43.7 (Ångstroms)

α = 90.0   β = 90.0   γ = 120.0 (degrees)

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.225 for 2503 reflections in the resolution range 5.0 to 1.5 Ångstroms with Fobs >  3.0 sigma(Fobs) and with I >  0.0 sigma(I)
