== Publication Abstract from PubMed ==
Bacteriophage T4 and related viruses have a contractile tail that serves as an efficient mechanical device for infecting bacteria. A three-dimensional cryo-EM reconstruction of the mature T4 tail assembly at 15-A resolution shows the hexagonal dome-shaped baseplate, the extended contractile sheath, the long tail fibers attached to the baseplate and the collar formed by six whiskers that interact with the long tail fibers. Comparison with the structure of the contracted tail shows that tail contraction is associated with a substantial rearrangement of the domains within the sheath protein and results in shortening of the sheath to about one-third of its original length. During contraction, the tail tube extends beneath the baseplate by about one-half of its total length and rotates by 345 degrees , allowing it to cross the host's periplasmic space.
