CC   -!- FUNCTION: P protein is probably the ATPase subunit of the terminase
CC       which directs cos cleavage. The Q, P and M proteins are needed to
CC       package DNA into proheads and for the conversion of proheads to
CC       capsids.
CC   -!- SIMILARITY: To phage HP1 protein ORF16. {ECO:0000305}.
