Cell Constants:

a = 61.98   b = 61.98   c = 159.07 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 1.2 program. The R value is 0.259 for 16027 reflections in the resolution range 20.0 to 2.7 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
