CC   -!- FUNCTION: Carries out the completion of filled heads by rendering the
CC       newly packaged DNA in filled heads resistant to DNase. The protein is
CC       assumed to bind to DNA-filled capsids.
CC   -!- DEVELOPMENTAL STAGE: Acts late in the assembly process.
CC   -!- SIMILARITY: To phage HP1 protein ORF20. {ECO:0000305}.
CC   -!- CAUTION: It is uncertain whether Met-1 or Met-2 is the initiator.
CC       {ECO:0000305}.
