Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 31.8   b = 91.0   c = 280.1 (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 0.222 for 11257 reflections in the resolution range 29.85 to 3.2 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
