CC   -!- FUNCTION: Component of the cylindrical core that assembles on the inner
CC       surface of the capsid during capsid formation and plays a role in viral
CC       DNA ejection into the host cell. The inner core is composed of stacked
CC       rings of gp14, gp15 and gp16 proteins. Following binding to the host
CC       cell surface, the internal core is disassembled and gp15 is ejected
CC       along with gp14 and gp16 into the infected cell. Gp15 probably remains
CC       associated with gp16. The gp15-gp16 complex binds to both the viral DNA
CC       and the host inner membrane, probably escorting the leading end of the
CC       genome through the periplasm and controlling the extend of DNA
CC       translocated into the host cell.
CC   -!- SUBUNIT: Homooctamer. Interacts with gp16; after ejection the gp15-gp16
CC       complex composed of a gp15 octamer and a gp16 tetramer probably binds
CC       both the viral DNA and the host inner membrane. Interacts with gp14.
CC   -!- SUBCELLULAR LOCATION: Virion. Host periplasm. Note=The gp15-gp16
CC       complex spans the periplasm and the cytoplasmic membrane.
CC   -!- SIMILARITY: Belongs to the T7virus internal virion protein gp15 family.
