In this Letter, the 60-subunit protein assembly presented more strongly resembles a wireframe dodecahedron than an icosahedron. We thank the reader who drew this to our attention and we agree that all instances of the word “icosahedron” should be changed to “dodecahedron”. In addition, “20 pentameric faces” in the boldface first paragraph should have read “12 pentagonal faces”, and throughout the text “pentameric faces” should have read “pentagonal faces”. The original Letter has not been corrected.
