Values in parentheses are for the highest resolution shell. NAT represents the native structure, GD the gem-diamine structure, IAA the internal aldimine structure with a product alanine, and PSF the persulfide-bound structure. , where is the mean intensity of ith observation of symmetry-related reflections hkl. I/σ (I) represents a signal to noise of reflections. where is the calculated protein structure factor from the atomic model ( was calculated with randomly selected 5% of the reflections). was calculated with the remaining 95% of the reflections in the same equation of . RMSD represents root-mean-square deviation. n.a.: not available. |
