X-RAY DIFFRACTION

Space Group:

P 43 21 2

Cell Constants:

a = 58.112   b = 58.112   c = 441.926 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 1.1 program. The R value is 0.236 for 19376 reflections in the resolution range 10.0 to 2.8 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
