Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 1 2 1

Cell Constants:

a = 195.502   b = 68.094   c = 73.587 (Ångstroms)

α = 90.0   β = 100.62   γ = 90.0 (degrees)

Refinement:

The structure was refined using the PHENIX (phenix.refine) program. The R value is 0.1735 for 22561 reflections in the resolution range 28.686 to 2.8 Ångstroms with Fobs >  0.09 sigma(Fobs) and with I >  0.0 sigma(I)
