  1. a Highest resolution shell is shown in parenthesis. Rsym = ΣhΣi|Ih,i − Ih|/ΣhΣiIh,i, where Ih is the mean intensity of the i observations of symmetry related reflections of h. R = Σ|Fobs − Fcalc|/ΣFobs, where Fobs = Fp, and Fcalc is the calculated protein structure factor from the atomic model. RMSD in bond lengths and angles are the deviations from ideal values
