CC   -!- FUNCTION: Although P4 acquires its capsid proteins from helper phages
CC       such as P2, it possesses the ability to assemble capsids that are only
CC       one-third the size of the helper's capsid. The sid protein is
CC       responsible for the assembly of P4-sized shells. It forms a P4-specific
CC       scaffold with icosahedral symmetry on the outside of the procapsid-like
CC       particles. {ECO:0000269|PubMed:7643390}.
