Movie S1.

Double jelly-roll core compaction and tower expansion in mavirus MCP upon processing. The morph was generated between flMCP and MCPΔC crystal structures (PDB ID 6G45 and 6G44, respectively) of capsomers using Pymol (PyMOL Molecular Graphics System, Schrödinger, LLC). Areas of jelly-roll 1 that undergo core compaction are colored dark green. The expanding part of tower 2 is shown in light green. The view on the capsomer corresponds with the representation in Fig. 2D in the main text.
