Using the defocus parameters, Cs (0.003, after Cs image corrector tuning) and amplitude contrast (0.1), CTF phase flipping and amplitude correction was performed during the reconstruction using Relion 2.1.
詳細: PDB file was converted to EM map using e2pdb2mrc.py routine in EMAN2 software package. The reference map was lowpass filtered to 60 angstroms as a startup model.
