Cocrystal structure of a class I preQ1 riboswitch reveals a pseudoknot recognizing an essential hypermodified nucleobase 
Nat.Struct.Mol.Biol., 16, pp. 343 - 344, 2009.

Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 32 2 1

Cell Constants:

a = 78.208   b = 78.208   c = 85.22 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 1.2 program. The R value is 0.0 for 7122 reflections in the resolution range 30.0 to 2.85 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
