Supplementary Figure 9: Three-dimensional classification of the C. elegans separase–securin complex.
From: Cryo-EM structure of a metazoan separase–securin complex at near-atomic resolution

The three-dimensional classification was conducted using 665,331 motion-corrected particles that were divided into six classes. The resultant classes did not reveal any major structural rearrangements or classes of free separase. The best-defined and most complete densities were selected for future reconstructions to further improve map quality.
