The six bacteriophage T7 tail fibers, homo-trimers of gene product 17, are thought to be responsible for the first specific, albeit reversible, attachment to Escherichia coli lipopolysaccharide.
Pigtail, also known as pigtail, has only one end with a connector, and the other end is a broken end of a fiber optic cable core. It is connected to other
Here, we introduce RBPseg, a method that combines monomeric ESMFold predictions with a structural-based domain identification approach, to
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
These adhesin sequences are highly variable in both their sequence and specificity for bacterial receptors. The tail fiber adhesin domains are located in different genes in closely related
S1 Fig: Alignment of Pseudomonas R tail fibers reveals three distinct clusters. Complete genomes from the Pseudomonas Genome Database were queried by DIAMOND BLASTP using the
The structure of C24 partially resembles that of the receptor-binding tip from the bacteriophage T4 long tail fiber (Bartual et al., 2010b), although there are notorious differences in
Bacteriophage T4 belongs to this sub-family and has a very high efficiency of infection, likely due to its complex tails and two sets of host-cell binding fibers (Figure 1).
T4 virion also contain two types of fibers: six short tail fibers (STFs), which are folded beneath the baseplate, and six long tail fibers (LTFs), attached to the
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
This study sheds some light on the mechanism underlying the conversion of phage T5 straight tail fiber Pb2 from a phage-attached protein to a membrane-active polypeptide.
Bacteriophage lambda is an excellent model system to study the tail architecture of bacteriophages. Wang et al. present the
F-type phage-tail like bacteriocins (PTLBs) are protein complexes with bactericidal activity and share similarity with non-contractile phage tails.
Genes (g) 36 and 37 code for the proteins of the distal half of the long tail fibers of phage T4, gene product (gp) 35 links the distal half to the proximal half of this fiber. The receptor, lipopolysaccharide,
The type VI secretion TssEFGK-VgrG phage-like baseplate is recruited to the TssJLM membrane complex via multiple contacts and serves as assembly platform for tail tube/sheath
It is shown that adsorbability of T4 is regularly correlated with the extended state of the tail fibers, suggesting that in T4 fiber extension is a necessary condition for adsorption. Furthermore the
An open reading frame in the Escherichia coli bacteriophage lambda genome encodes a protein that functions in assembly of the long tail fibers of
The tail fiber has its unique fiber optic head, connecting to the fiber optic transceiver and linking the fiber optic and twisted pair to the information socket.
Here, we discuss the molecular mechanisms and models of the tail fibers of the well-characterized T4 phage''s interaction with host surface receptors.
Introduction T-even bacteriophages have remarkably complex contractile tails with six long tail fibers attached to a hexagonal baseplate. It has been demonstrated by electron microscopy that
Organization of the bacteriophage T4 long tail fiber. (A) A structural model of bacteriophage T4 virion showing the head, the tail, and the long tail fibers.
To acquire atomic-level structural details, the tail particles were divided into three distinct reconstructions: tail cap, tail tip, and
Short tail fibres of T-even like phages are involved in host recognition. To determine the specificity of the fibres, the region containing gene 12 of phages T2, K3, and K3hx was cloned. The genes 11, 12,
The sequences of the tail fiber protein 36 of the phages T 4, T 2, K 3, and Ox 2 were analyzed for homologies and for folding patterns using structure prediction methods.
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
The authors present the nearly-complete structure of the DT57C bacteriophage of the Siphovirus family, revealing the molecular architecture of its capsid, neck, tail and tail tip, and
Mosaic modularity of R-type bacteriocin tail fiber sequence contributes to competitive ability in strains of Xenorhabdus bovienii.
Siphoviridae and Podoviridae additionally have a central tail fibre or spike that protrudes from the distal end of the tail or baseplate.
Bacteriophage libraries containing millions of variants of phage tail fiber motifs on a common structural scaffold give rise to infectious phages with
