  2. Bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Bacteriophage

    An example of a bacteriophage known to follow the lysogenic cycle and the lytic cycle is the phage lambda of E. coli. [53] Sometimes prophages may provide benefits to the host bacterium while they are dormant by adding new functions to the bacterial genome, in a phenomenon called lysogenic conversion.

  3. Type VI secretion system - Wikipedia

    en.wikipedia.org/wiki/Type_VI_secretion_system

    The tubules consist of repeating units of the proteins TssA and TssB (VipA/VipB) arranged as a sheath around a tube built from stacked hexameric rings of the haemolysin co-regulated protein (Hcp). [ 12 ] [ 13 ] At the tip of the Hcp tube sits a trimer of the phage tail spike-like protein VgrG, which is in turn capped by a pointed PAAR domain ...

  4. Caudoviricetes - Wikipedia

    en.wikipedia.org/wiki/Caudoviricetes

    The virus particles have a distinct shape; each virion has an icosahedral head that contains the viral genome, and is attached to a flexible tail by a connector protein. [2] The order encompasses a wide range of viruses, many containing genes of similar nucleotide sequence and function.

  5. Escherichia virus T4 - Wikipedia

    en.wikipedia.org/wiki/Escherichia_virus_T4

    The species was formerly named T-even bacteriophage, a name which also encompasses, among other strains (or isolates), Enterobacteria phage T2, Enterobacteria phage T4 and Enterobacteria phage T6. Use in research

  6. Filamentous bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Filamentous_bacteriophage

    Assembled major coat protein subunits in Ff (fd, f1, M13) filamentous bacteriophage (genus Inovirus), exploded view. Filamentous phage virion--schematic views. Filamentous bacteriophages are among the simplest living organisms known, with far fewer genes than the classical tailed bacteriophages studied by the phage group in the mid-20th century.

  7. Virion - Wikipedia

    en.wikipedia.org/wiki/Virion

    Multiple shapes of virions. Since the genome of viruses is relatively simple, the capsid architecture relies on repetition of simple structures, similar to the faces of a polyhedron. Each face in turn is formed by a repetition of simpler sub-units, with the amount of repetitions called a triangulation number (T). Similar capsid structures can ...

  8. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    Bacteriophage Lambda Structure at Atomic Resolution [1] Enterobacteria phage λ (lambda phage, coliphage λ, officially Escherichia virus Lambda) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli (E. coli). It was discovered by Esther Lederberg in 1950. [2]

  9. Capsid - Wikipedia

    en.wikipedia.org/wiki/Capsid

    The prolate structure of a typical head on a bacteriophage. An elongated icosahedron is a common shape for the heads of bacteriophages. Such a structure is composed of a cylinder with a cap at either end. The cylinder is composed of 10 elongated triangular faces.
