Cell Constants:

a = 184.124   b = 103.319   c = 295.646 (Ångstroms)

α = 90.0   β = 98.96   γ = 90.0 (degrees)

Refinement:

The structure was refined using the PHENIX program. The R value is 0.1924 for 100013 reflections in the resolution range 25.265 to 2.9 Ångstroms with Fobs >  1.49 sigma(Fobs) and with I >  0.0 sigma(I)
