CC   -!- FUNCTION: Polymerizes as an extended structure around the baseplate-
CC       tail tube complex. During ejection, the sheath shifts to a contracted
CC       form, thereby making the inner tail tube protrude through the host cell
CC       envelope. {ECO:0000250|UniProtKB:P79678}.
CC   -!- SUBUNIT: Homomultimer. {ECO:0000250|UniProtKB:P79678}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:P79678}. Host
CC       cytoplasm {ECO:0000250|UniProtKB:P79678}. Note=Tail.
CC       {ECO:0000250|UniProtKB:P79678}.
CC   -!- SIMILARITY: Belongs to the myoviridae tail sheath protein family.
CC       {ECO:0000305}.
