CC   -!- FUNCTION: Minor spike component of the viral shell. Involved in the
CC       ejection of the phage DNA in the host and is injected with the DNA in
CC       the periplasmic space of the host. Involved in the determination of the
CC       phage host-range (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: The virion is composed of 60 copies each of the F, G, and J
CC       proteins, and 12 copies of the H protein. There are 12 spikes which are
CC       each composed of 5 G and one H proteins.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
