Name, Synonyms and Lineage

Virus is the type species of the genus "SP01-like Phages; family 02.043. Myoviridae; order 02. Caudovirales.

Virion Properties

Morphology

Phages consist of a head and a tail and are not enveloped. Phage has a head with icosahedral symmetry and a tail with helical symmetry. The symmetry of the head is derived from a basic icosahedral structure by adding rows of capsomers to the capsid (T=13). The head is prolate in shape and has a diameter of 75-100 nm. Capsids appear hexagonal in outline. The capsid consists of 152 capsomers. The contractile, tubular tail is rigid, long and thick with cross-bands and has a a length of 130-165 nm and a width of 16-20 nm. Axial canal is distinct. Basic helix is obvious. Tail has a collar, a base plate, spikes, fibers, and a sheath, which is separated from the head by a neck; sheath is composed of stacked rings; during contraction, sheath subunits of contractile tails slide over each other (and the sheath becomes shorter and thicker, sheath is 60-75 nm long when contracted; 6 fibers; fibers are long; fibers are terminal; 6 spikes; spikes are short; base plate is small; central core of phage tail helical.

Nucleic Acid

The Mr of the genome constitutes 48% of the virion by weight. The genome is not segmented and contains a single molecule of linear double-stranded DNA. The complete genome is 140000-151200 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 140000-151200 nucleotides long. The genome has a guanine + cytosine content of 35 %. The genome contains unusual bases, they are 5-hydroxy-methyl cytosine. Double stranded DNA is circularly permuted. The genome has terminally redundant sequences.

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses by Dr Cornelia Büchen-Osmond is written in DELTA. The virus descriptions in ICTVdB are coded by, or using data from experts in the field of virology or members ICTV. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations are automatically generated and formatted for display on the Web from the descriptions in DELTA-format. The description has been generated automatically from DELTA files.
