Difference of Gaussian (DOG)-based automated particle picker, implemented in Appion processing package was used for particle selection.
 CTFFIND4
Ctffind4 was used for determining the CTF of each micrograph. Phases of each micrographs were flipped before particle extraction.
PHASE FLIPPING ONLY 2QLD
Four copies of PDB 2QLD were overlaid on 2D classes and low pass filtered to generate an initial 3D model.
