Name, Synonyms and Lineage

ICTV approved acronym: NωV. Virus is the type of the genus 00.070.0.02. Omegatetravirus in the family 00.070. Tetraviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry (T=4). The capsid is isometric and has a diameter of 41.6-43.4 nm. Capsids appear hexagonal in outline. The capsomer arrangement is clearly visible (in cryo-electron microscopy).

Physicochemical and Physical Properties

The molecular mass (Mr) of virions is 16 x 106. The thermal inactivation point (TIP) is at 55°C. Under in vitro conditions virions are stable in acid environment of pH 3; stable in alkaline environment of pH 11.

Nucleic Acid

The Mr of the genome constitutes 11% of the virion by weight. The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA. The RNA-1 is partially sequenced and sequenced, but only an estimate is available, complete sequence is 5300 nucleotides long and sequenced region is 2448 nucleotides long. RNA-2 is fully sequenced. Complete sequence is 2448 nucleotides long and encodes coat protein has the accession number [S43937]. The 3'-terminus has no poly (A) tract. The 3'-terminus has a tRNA-like structure. The multipartite genome is likely to be found in one type of particle only.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins. Virions consist of 1 structural protein located in the capsid.

Structural Proteins: Capsid protein CP has a molecular mass of 69863 Da with 120 copies per virion (precursor proteins and 240 protomers), sequence has the accession number [Q90063]; is the coat protein; has been cleaved during post-translational processing from the precursor protein (each protomer consists of the two cleavegae products (Mr 62 x 103 and 7.8 x 103) of a single CP precursor).

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.
