Electron micrographs were recorded with low dose
KODAK SO-163 FILM ZEISS SCAI 7
Micrographs were digitized on a Zeiss SCAI scanner at a pixel size of 7 microns, corresponding to 1.667 angstroms on the specimen. Subsequently, adjacent pixels were 3 x 3 averaged to yield a pixel size of 5 angstroms.
 eucentric 0 50 C1 SPIDER
The tilted images were corrected for the effects of the contrast transfer function (CTF) by phase flipping, taking into account the defocus gradient across the micrographs and the position of each particle. Images were processed using SPIDER version 11.12 and 15.06. Three-dimensional reconstruction was performed by the random conical tilt method in SPIDER. The particles were windowed into 64 x 64 pixel boxes.
