Fig. 3: Cryo-EM reconstructions of bovine PDC and atomic structure of native E2p IC domain.

a 3D reconstruction of the full PDC with icosahedral symmetry shows external densities (orange) around the core density (gray). b Two views of the cryo-EM density map of E2p core colored by radius, with our E2p atomic model assembly of a hemisphere shown in the left panel. c Rainbow-colored ribbon of E2p IC domain atomic model with secondary structures labeled. Resolvable N-terminal residues (blue) and C-terminus (red) are indicated. d Two views of the atomic model of the E2p IC domain trimer, colored by subunits.
