CC   -!- FUNCTION: Head completion protein that closes the capsid once the viral
CC       DNA has been packaged. Probably part of the head-tail connector by
CC       binding to the portal protein and to the tail completion protein.

CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000269|PubMed:24198424}. Note=Minor
CC       protein of the capsid. {ECO:0000269|PubMed:24198424}.
