Other Details FOR VISUALIZATION PURPOSES THE FINAL MAP WAS FILTERED AND AMPLITUDE CORRECTED IN RELION SUBMISSION BASED ON EXPERIMENTAL DATA FROM EMDB EMD-2787. (DEPOSITION ID: 12830). THE COMBINED COORDINATES (SPLIT ENTRIES 4V19 AND 4V1A) WERE REFINED IN RECIPROCAL SPACE USING PHENIX.REFINE AGAINST THE MLHL TARGET. FOR THIS, THE CRYO-EM MAPS (EMD-2787) WERE CONVERTED TO RECIPROCAL SPACE STRUCTURE FACTORS.
