Metal ions and flexibility in a viral RNA pseudoknot at atomic resolution. 
Proc.Natl.Acad.Sci.USA, 99, pp. 4302 - 4307, 2002.

Experimental Information:

X-RAY DIFFRACTION

Space Group:

I 21 3

Cell Constants:

a = 107.81   b = 107.81   c = 107.81 (Ångstroms)

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

Refinement:

The structure was refined using the CNS program. The R value is 0.0 for 4989 reflections in the resolution range 20.0 to 2.85 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
