The tail structure of bacteriophage T4 and its mechanism of
A three-dimensional cryo-EM reconstruction of the mature T4 tail assembly at 15-Å resolution shows the hexagonal dome-shaped baseplate, the extended contractile sheath, the long
Read MoreHome / The outer sheath of the tail fiber is a bit stiff
Upon attachment to a bacterial cell, the sheath contracts, driving the tail tube through the host's cell envelope and injecting the viral genome into the cell. The subunits that form three of the six neighbouring helices (pink, A; blue, B; and green, C) within the sheath are shown as surface representations of (A) the extended and (B) the contracted sheath. Structurally these viruses have a prolate icosahedral capsid (the head) attached at one vertex to a long.

Read MoreThe tail consists of a rigid sheath surrounding an inner tail tube. Upon attachment to a bacterial cell, the sheath contracts, driving the tail tube through the host''s cell
Read MoreIts major component is a tail sheath, which contracts during infection to less than half of its initial length.
Read MoreA tail sheath is a specialized, contractile protein structure in certain bacteriophages that surrounds the central tail core, critical for injecting viral genetic material into the host cell.
Read MoreThe tail tubes of bacteriophages phi29 and P68 are composed of a 24-stranded β barrel attached to a pseudo-hexametric tail knob.
Read MoreFor injection-molded cable products such as optical cables, surface defects are a common product quality problem. There are many types of defects, and common cable surface defects
Read MoreSimilar to fiber optic jumpers, tail fibers are classified into single-mode and multimode types, differing in color, wavelength, and transmission distances. Generally, multimode tail fibers are

Read MoreThe 980 Å-long, 220 Å diameter central cylindrical segment of the tail consists of a rigid tube, composed of multiple copies of gp19, surrounded by the outer contractile sheath assembled from gp18 subunits
Read MoreThe color of the outer sheath of the multimode pigtail is orange, the wavelength is 850nm, and the transmission distance is 500m, which is used for
Read MoreBacteriophage T4 initially recognizes its host cells using its long tail fibers. Long tail fibers consist of a phage-proximal and a phage-distal rod, each around 80 nm
Read MoreDuring the infection process, it is thought that the binding of the long tail fibers to the cell surface induces a conformational change in the baseplate (going from the high energy, dome-shaped state to the low
Read MoreWhat is the purpose of the sheath of a bacteriophage? The sheath consists of 138 copies of the tail sheath protein, gene product (gp) 18, which surrounds the central non-contractile tail tube.
Read MoreBacteriophage T4 and related viruses have a contractile tail that serves as an efficient mechanical device for infecting bacteria.
Read MoreDifferent phages have tail fibers designed to recognize and bind to unique receptors found on specific bacterial strains or species. For instance, the long tail fibers of T4 phage determine its
