R merge = , where Ii(hkl) is the intensity of the ith observation of reflection hkl and I(hkl) is the weighted average of all i observations of reflection hkl.
The lowest resolution shell was 48.398.72 for the native crystal and 48.398.29 for the holmium-bound crystal.
The Ramachandran plot statistics were obtained from the MolProbity server (Chen et al., 2010 ▶).
