Taxonomic Proposals and Changes
A taxonomic
proposal has been submitted to the ICTV by the Vertebrate Virus Subcommittee
Study Group for Retroviridae at the meeting in
Washington, DC, April 2001 and Paris, July 2002, to reclassify the
position of Type Species. The proposal has been approved at the
meeting of the Executive Committee in Paris, 2002, and the taxon has been
designated as Type Species .
Virions have a complex construction and consist of an
envelope, a nucleocapsid, a nucleoid, and a matrix protein. Virions are
enveloped, spherical to pleomorphic in shape and measure
80-100 nm in diameter. The surface projections are distinctive
spikes that are densely dispersed evenly covering the surface. The core is spherical. The nucleoid is concentric. Only one type of virus particle is recovered in preparations.
The Mr
of the genome constitutes 2% of the virion by weight. The genome is dimeric; not
segmented and consists of a single molecule of linear,
positive-sense, single-stranded RNA. The complete genome is of one monomer 11000 nucleotides long and has been fully
sequenced with the accession number
[M74895]. The genome
has terminally redundant sequences. The terminally redundant sequences have long
terminal repeats (LTR) of about 1500 nt. The 5'-end of the genome has a
methylated nucleotide cap with a type 1 sequence of
m7G5ppp5'GmpNp. The 3'-terminus has of each monomer a poly (A) tract
and a tRNA-like structure that accepts lysin. Each virion
contains two copies of the genome in a dimeric configuration.
Lipids are
present and located in the envelope. Virions are composed of 35%
lipids by weight. The composition of viral lipids and host cell membranes are
similar. The lipids are of host origin derived from plasma
membranes.
Carbohydrates
Three percent of the particle weight are attributed to carbohydrates.
Genome Organization and Replication
By
itself, genomic nucleic acid is not infectious.
Translation: Replication involves a
reverse transcription step.
Biological Properties
Natural Host
Range
Virus infects during its life cycle a single type of vertebrate host.
Viral hosts belong to the Domain Eucarya.

ICTVdB - The Universal Virus
Database, developed for the International Committee on Taxonomy of
Viruses (ICTV) by
Dr Cornelia Büchen-Osmond, is written in DELTA. The virus descriptions
in ICTVdB are coded by ICTV members and experts, or by the
ICTVdB Management using data provided by the experts, the literature or the
latest ICTV Report. The character list is the
underlying code. All virus descriptions are based on the character list and
natural language translations from the encoded descriptions are automatically
generated and formatted for display on the Web.
