Table of Contents

Classification

This is a description of an archaeal virus at the genus level.

ICTVdB Virus Code: 00.038.0.01. Virus accession number: 038001GE. Obsolete virus code: 38.0.1.; superceded accession number: 38010000.
NCBI Taxon Identifier NCBI Taxonomy ID: 341939.

Name, Synonyms and Lineage

Synonym(s): TTV1 Group. Virus is of the family 00.038. Lipothrixviridae.

Virion Properties

Morphology

Virions consist of an envelope and a nucleocapsid. Virus capsid is enveloped. Virions are rod-shaped and rigid, have protrusions extending from the core through the envelope that arise asymmetrically from both ends. Virions measure 38 nm in diameter and 410 nm in length with a tight fitting membrane. The envelope has no surface projections. Capsid/nucleocapsid is elongated and exhibits helical symmetry. The core is helical.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.25 g cm-3.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear double-stranded DNA. The complete genome is 16000 nucleotides long.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins, non-structural proteins, and proteins found only in infected host cell.

Lipids

Lipids are present and located in the envelope. The composition of viral lipids and host cell membranes are identical. The lipids are of host origin and are derived from host cell membranes. Lipids in the viral membrane have a bilayer structure. Viral membranes include glycolipids and phospholipids, di-phytanyl tetraethers lipids; the phosphate residues of phospholipids are oriented towards the inside of the particle; the glycosyl residues of glycolipids are oriented towards the outside of the particle.

Biological Properties

DELTA - DEscription Language for TAxonomy developed by Dr Mike Dallwitz, Toni Paine and Eric Zurcher, CSIRO Entomology, Canberra, Australia. 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.
