Structure of the siphophage neck–Tail complex suggests
Here, we present the structure of the siphophage lambda "wild type," the most widely used, laboratory-adapted fiberless mutant. The neck–tail complex

Here, we discuss the molecular mechanisms and models of the tail fibers of the well-characterized T4 phage''s interaction with host surface receptors. Structure–function knowledge of tail fibers will pave
The baseplate-anchored short tail fibers (STFs) are then unpinned, rotate downward, and irreversibly bind to the lipid A-inner core region of LPS. The baseplate completes the conformation conversion
The gpJ trimer not only seals the tail tip into a closed cone but also extends a central tail fiber, providing the means through which lambda phage directly interacts with its host.
Moreover, the side tail fibers presumably slow down the diffusion of Ur-λ through the top agar layer, resulting in the smaller plaque size . However, how the side tail fibers affect phage
Here, Ge et al use cryo-electron microscopy to resolve the structure of the bacteriophage lambda tail in complex with its LamB receptor from Shigella sonnei and shed light on the
After recognition has occurred and the virus is bound to the bacteria, a variety of conformational changes allows the short tail fibers to bind to the outer region of the bacterial lipo-polysaccharide and
The Mu phage can recognize lipopolysaccharide (LPS) on the host cell surface via its tail fibers. LPS is a component of the outer membrane of Gram-negative bacteria and consists of three
Similar 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
Siphoviridae and Podoviridae additionally have a central tail fibre or spike that protrudes from the distal end of the tail or baseplate.
Bacteriophage 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 long and attached to each
Bacteriophage 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
The Myoviridae phage tail is a common component of contractile injection systems (CISs), essential for exerting contractile function and facilitating membrane penetration of the inner
Depending on the morphology of their tail, phages are classified as Siphoviridae (long flexible tail), Myoviridae (long contractile tail) and Podoviridiae (short tail). The assembly pathway of
The baseplate-anchored short tail fibers (STFs) are then unpinned, rotate downward, and irreversibly bind to the lipid A-inner core region of LPS. The
Twelve tail fibers or appendages extend from and hang around the bulge at the junction of the head and the tail [7••, 8••, 36, 40]. The tail tube is assembled by 12 copies of one tail protein, of
Phage G is recognized as having a remarkably large genome and capsid size among isolated, propagated phages. Negative stain electron
Bacteriophage lambda is an excellent model system to study the tail architecture of bacteriophages. Wang et al. present the cryo-EM structures of the components of the bacteriophage
Collectively, scientists call this network of protein fibers the cytoskeleton. There are three types of fibers within the cytoskeleton: microfilaments, intermediate
To acquire atomic-level structural details, the tail particles were divided into three distinct reconstructions: tail cap, tail tip, and tail fiber (Figure 1 B).
Here we present the crystal structure of the receptor-binding tip of the bacteriophage T4 long tail fiber, which is highly homologous to the tip of the
Bacteriophages are the most numerous organisms in the biosphere. In spite of their biological significance and the spectrum of potential applications,
Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu.
This complex machinery often includes a contractile sheath surrounding an inner core, a baseplate at the tail''s distal end, and several tail fibers. Upon encountering a susceptible bacterial
The Myoviridae family in this order is characterised by tails with a contractile outer sheath, which drives an inner tail tube through the bacterial cell wall. Once this tube has cut through the cell wall the
These hollow elongated protein structures, present in most bacteriophages of the order Caudovirales, connect the DNA-containing capsid with a receptor function at the distal end of the tail
At the far end of the tail are one or more receptor binding proteins (the tail fibers), also described as adhesins.
The bacteriophage ϕ29 infects Gram-positive Bacillus subtilis with a short noncontractile tail. Recent studies showed that the ϕ29 tail protein gp9 forms a hexameric tube with six long loops of membrane
The phage tail tape measure protein, an inner membrane protein and a periplasmic chaperone play connected roles in the genome injection process of E. coli phage HK97.
