THE C3 SYMMETRY (AS IN THE EM MAP EMD-2987) SHOULD BE APPLIED IN ORDER TO DISPLAY THE WHOLE ASSEMBLY. FOR THIS, PLEASE ADD THE REMARK 350 BIOMT AS IN THE UPLOADED FILE. DUE TO LOW RESOLUTION OF THE EM MAP USED FOR FITTING, WE DEPOSIT ONLY THE BACKBONE ATOMS. SUBMISSION BASED ON EXPERIMENTAL DATA FROM EMDB EMD-2987. (DEPOSITION ID: 13341).
