Every image is the average of 30 frames recorded using the K2 Summit. The final reconstruction was calculated from images motion-corrected and weighted using the method described in Scheres 2014.
The particles were selected using an automatic selection program and manually screened. Defocus was calculated using CTFFIND3. Data were processed and refined using RELION 1.3.
