It is a T4 long fiber, which is highly homologous to the tip of the bacteriophage lambda side tail fibers. This structure reveals an unusual elongated six-stranded antiparallel beta-strand needle domain containing seven iron ions coordinated by histidine residues arranged colinearly along the core of the biological unit. At the end of the tip, the three chains intertwine forming a broader head domain, which contains the putative receptor interaction site. The structure reveals a previously unknown beta-structured fibrous fold, provides insights into the remarkable stability of the fiber, and suggests a framework for mutations to expand or modulate receptor-binding specificity.
The tail fiber of a bacteriophage is a protein structure located at the end of the phage's tail that helps the virus recognize and bind to specific receptors on the surface of its host bacterium. This interaction is essential for the bacteriophage to infect the host cell and inject its genetic material. The tail fiber is a key component of the bacteriophage's ability to recognize and infect its target bacteria.

What is the tail of a bacteriophage specialized for?
The tail of a bacteriophage is specialized for attaching to the host bacterial cell and injecting its genetic material into the cell. It helps the bacteriophage in recognizing and binding to specific receptors on the bacterial cell surface.
Is a virus that infects bacteria called bacteriophage?
bacteriophage
What is the tail fiber in a virus?
It's a T4 long fiber and it attaches to the cell wall of the host
When viruses infect bacteria what is it called?
A bacteriophage
What is a bacteriophage?
A bacteriophage is a kind of virus that infects and kills bacteria.a virus that attacks bacteria
Which structure would a bateriophage use to attach itself to the outside of a bacterial cell?
The general structure of a bacteriophage includes a head, tail sheath, and tail fiber. It uses its tail fibers to bind to a receptor site of a bacteria cell.

No. A bacteriophage is a virus that attacks bacteria.
Scientific name for bacteriophage?
The scientific name for bacteriophage is "virulent bacteriophage" or "bacterial virus." Bacteriophages are viruses that infect and replicate within bacteria cells.
What is the genetic material of a bacteriophage?
1. Size - T4 is among the largest phages; it is approximately 200 nm long and 80-100 nm wide. Other phages are smaller. Most phages range in size from 24-200 nm in length.2. Head or Capsid - All phages contain a head structure which can vary in size and shape. Some are icosahedral (20 sides) others are filamentous. The head or capsid is composed of many copies of one or more different proteins. Inside the head is found the nucleic acid. The head acts as the protective covering for the nucleic acid.3. Tail - Many but not all phages have tails attached to the phage head. The tail is a hollow tube through which the nucleic acid passes during infection. The size of the tail can vary and some phages do not even have a tail structure. In the more complex phages like T4 the tail is surrounded by a contractile sheath which contracts during infection of the bacterium. At the end of the tail the more complex phages like T4 have a base plate and one or more tail fibers attached to it. The base plate and tail fibers are involved in the binding of the phage to the bacterial cell. Not all phages have base plates and tail fibers. In these instances other structures are involved in binding of the phage particle to the bacterium.
