Fitting Procedure ?
Details Chain A of PDB 4PMW (MmDis3L2) was fit into the map via rigid body fitting. Residues were then mutated to match the human protein and manual building done to correct for differences. Next rounds of refinement and building were done in PHENIX and Coot, respectively, until the final structure was obtained.
