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 ...
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.
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.
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.
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
Mycobacteriophage Bxb1 Structure [1]. A mycobacteriophage is a member of a group of bacteriophages known to have mycobacteria as host bacterial species. While originally isolated from the bacterial species Mycobacterium smegmatis and Mycobacterium tuberculosis, [2] the causative agent of tuberculosis, more than 4,200 mycobacteriophage species have since been isolated from various environmental ...
The main structural component of Bacteriophage AP205 in the Fiersviridae family is a protein shell. Viruses in this family are not enveloped and are characterized by their icosahedral and spherical shape. The icosahedron shape of the capsid results from the arrangement of 178 copies of the coat protein which provide the virus with its structure ...
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]
