C 1 2 1

Cell Constants:

a = 93.793   b = 103.241   c = 69.583 (Ångstroms)

α = 90.0   β = 97.9   γ = 90.0 (degrees)

Refinement:

The structure was refined using the PHENIX (phenix.refine: 1.4_87) program. The R value is 0.2358 for 32745 reflections in the resolution range 23.014 to 2.1814 Ångstroms with Fobs >  0.03 sigma(Fobs) and with I >  0.0 sigma(I)
