EM Image Reconstruction Statistics
Number of Particles 35645
Other Details The entire ankyrin structure was fitted as a single rigid body. As a result, the first two ankyrin repeats (UNP residues 111-199) are included but are not well defined by the experimental density. (Single particle details: 3D classification, refinement, and reconstruction were performed using RELION) (Single particle--Applied symmetry: C4)
