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.
However, some tailed bacteriophage genomes can vary quite significantly in nucleotide sequence, even among the same genus. Due to their characteristic structure and possession of potentially homologous genes, it is believed these bacteriophages possess a common origin.
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]
The phage tail-like tubule of the T6SS assembles on a structure analogous to bacteriophage baseplates. It consists of the proteins TssE, TssF, TssG, and TssK. The baseplate and phage tail-like complex interact in the bacterial cytoplasm, and then are recruited to the cell envelope by the membrane complex.
Φ6 (Phi 6) is the best-studied bacteriophage of the virus family Cystoviridae. It infects Pseudomonas bacteria (typically plant-pathogenic P. syringae ). It has a three-part, segmented, double-stranded RNA genome , totalling ~13.5 kb in length.
Tailed bacteriophage structure: (1) head, (2) tail, (3) DNA, (4) capsid, (5) collar, (6) sheath, (7) tail fibres, (8) spikes, (9) base plate. In some groups of viruses - such as the class Caudoviricetes ("tail viruses") and the genus Tupanvirus - the capsid carries an appendage called the "tail". The tail of the Caudoviricetes is usually ...
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 ...
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.
