CC   -!- FUNCTION: Attaches the circulating virion to the bacterial
CC       lipopolysaccharides which serve as receptor for the virus. Determines
CC       the phage host-range. Probably triggers with protein H the injection of
CC       the phage DNA into the host cytoplasm upon conformational changes
CC       induced by the interaction with host lipopolysaccharides (By
CC       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}.
CC   -!- SIMILARITY: Belongs to the microvirus G protein family. {ECO:0000305}.
