X-RAY DIFFRACTION

Space Group:

P 1 21 1

Cell Constants:

a = 77.437   b = 152.941   c = 125.244 (Ångstroms)

α = 90.0   β = 94.3   γ = 90.0 (degrees)

Refinement:

The structure was refined using the PHENIX program. The R value is 0.2048 for 57942 reflections in the resolution range 29.731 to 3.0 Ångstroms with Fobs >  1.36 sigma(Fobs) and with I >  0.0 sigma(I)
