  5. The spike protein, chain G, is small and compact and the capsid protein, chain F, is large. Four copies of a small scaffolding protein (chains 1, 2, 3 and 4) are arranged in the angle between the capsid and spike proteins, ending up on the outside of the final virus capsid. Another small scaffold protein (chain B) is found on the inside of the capsid, where it assists in the capture of DNA. (1cd3, 1999) “A Milestone at the PDB”, 2000, David S.
