Podoviridae
''Podoviridae'' is a family of bacteriophage in the order ''Caudovirales'' often associated with T-7 like phages. There are 130 species in this family, assigned to 3 subfamilies and 52 genera. This family is characterized by having very short, noncontractile tails. Podoviradae are largely understudied and most new isolates are of the phicbkviruses genus, a group of giant viruses that appear to be Caulobacter specific. Structure Viruses in ''Podoviridae'' are non-enveloped, with icosahedral and head-tail geometries. The diameter is around 60 nm, and consists of 72 capsomers. The head protein has a molecular mass of ~38 kiloDaltons and is present in 460 copies per virion. There are 9 structural proteins. The tail is non-contractile and has 6 short subterminal fibers. It is thick and rod-shaped and built of stacked disks. The maximum length is ~17 nm. The double stranded DNA genome is linear, around 40-42kb in length, and encodes ~55 genes. The guanine + cytosine Cy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caudovirales
''Caudovirales'' is an order of viruses known as the tailed bacteriophages (''cauda'' is Latin for "tail"). Under the Baltimore classification scheme, the ''Caudovirales'' are group I viruses as they have double stranded DNA (dsDNA) genomes, which can be anywhere from 18,000 base pairs to 500,000 base pairs in length. 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. The order encompasses a wide range of viruses, many containing genes of similar nucleotide sequence and function. 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. There are 14 families, 73 subfamilies, 927 genera, and 2,814 species in the order. This makes ''Caudovirales'' the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enquatrovirus
''Enquatrovirus'' is a genus of bacteriophages in the order ''Caudovirales'', in the family ''Podoviridae''. Bacteria serve as natural hosts. There is currently only one species in this genus: the type species '' Escherichia virus N4''. ''Escherichia virus N4'' is the type species of this genus and was originally isolated from sewers in Genoa, Italy and infects ''Escherichia coli'' K-12. Recently, a number of genetically related phages were isolated, infecting '' Silicibacter'' and '' Sulfitobacter'' (DSS3ɸ2 and EE36ɸ1) as well as a number of ''Pseudomonas'' phages (LUZ7, LIT1 and PEV2) Taxonomy Group: dsDNA Structure The virus's virion have icosahedral (T=9) heads ~70 nm and short tails (10 nm), and contain short fibers originating from the junction between the head and tail. All the phages of this genus are strictly virulent and contain a linear dsDNA genome (with terminal repeats) in the range of 70-75kb. Life cycle Viral replication is cytoplasmic. Entry into th ...

Bruynoghevirus
''Bruynoghevirus'' is a genus of viruses in the order ''Caudovirales'', in the family ''Podoviridae''. Bacteria serve as natural hosts. There are seven species in this genus. Taxonomy The following species are recognized: * '' Pseudomonas virus Ab22'' * '' Pseudomonas virus CHU'' * '' Pseudomonas virus LUZ24'' * '' Pseudomonas virus PAA2'' * '' Pseudomonas virus PaP3'' * '' Pseudomonas virus PaP4'' * '' Pseudomonas virus TL'' Structure Viruses in ''Bruynoghevirus'' are non-enveloped, with an icosahedral head (63 nm) and a short tail (12x8 nm). Although these phages produce small and turbid plaques, all attempts to isolate stable lysogenic ''P. aeruginosa P. is an abbreviation or acronym that may refer to: * Page (paper), where the abbreviation comes from Latin ''pagina'' * Paris Herbarium, at the ''Muséum national d'histoire naturelle'' * ''Pani'' (Polish), translating as Mrs. * The ''Pacific Repo ...'' clones failed.
