Classification

This is a description of a vertebrate virus at the species level.

ICTVdB Virus Code: 00.061.2.07.001. Virus accession number: 61207106. Former virus code: 00.061.0.07.001.; 61.0.7.0.001; accession number: 61007001; 61070001. NCBI Taxon Identifier NCBI Taxonomy ID: 11964 .

Name, Synonyms and Lineage

Synonym(s): Chimpazee foamy virus, human isolate. ICTV approved acronym: SFV-1. Virus is an ICTV approved species. Virus is of the genus 00.061.2.07. Spumavirus ; subfamily 00.061.2. Spumaretrovirinae ; family 00.061. Retroviridae .

Virion Properties

Morphology

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 species is recovered in preparations.

Nucleic Acid

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 RT-RNA. The RNA is fully sequenced and one monomer of the complete sequence is 11000 nucleotides long. Sequence has the accession number X54482]. 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; cap sequence type is of type 1 m7G5ppp5'GmpNp. The 3'–terminus has of each monomer a poly (A) tract. The 3'–terminus has a tRNA–like structure (and accepts lysin). Each virion contains two copies of the genome in a dimeric configuration.

GenBank records for nucleotide sequence(s); complete genome sequences.

Proteins

Proteins constitute about 60% of the particle weight.

The viral genome encodes structural proteins and non-structural proteins.

Non-Structural Proteins: The virus codes for an RNA-dependent DNA polymerase.

Lipids

Lipids are present and are 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 and are derived from plasma membranes.

Polyamines

Other compounds that have been detected in the virus particles are 3% carbohydrates.

Genome Organization and Replication

By itself, genomic nucleic acid is not infectious.

Translation: Replication involves a reverse transcription step.

Biological Properties

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; { } the taxon has been designated as Type Species.

Comments to ICTVdB Management

The description has been generated automatically from DELTA files.

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.

Developer of the DELTA software: M. J. Dallwitz, T. Paine and E. Zurcher
