Protein
Tail sheath protein
Organism
Clostridium phage phiCD119 (strain Clostridium difficile/United States/Govind/2006)
Function
Polymerizes as an extended structure around the baseplate-tail tube complex. During ejection, the sheath shifts to a contracted form, thereby making the inner tail tube protrude through the host cell envelope.
Similarity
Belongs to the myoviridae tail sheath protein family.
