CC   -!- FUNCTION: Probably triggers with protein G the injection of the phage
CC       DNA into the host upon conformational changes induced by virus-host
CC       receptor interaction. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the microviridae H protein family.
CC       {ECO:0000305}.
