X-RAY DIFFRACTION

Space Group:

P 1 21 1

Cell Constants:

a = 100.23   b = 138.96   c = 102.97 (Ångstroms)

α = 90.0   β = 105.33   γ = 90.0 (degrees)

Refinement:

The structure was refined using the PHENIX program. The R value is 0.2351 for 44474 reflections in the resolution range 29.884 to 3.201 Ångstroms with Fobs >  1.91 sigma(Fobs) and with I >  0.0 sigma(I)
