General Description

This is one of the genera in the family Anelloviridae and contains viruses of tamarin with a genome of 3.4 kb. The genus name is partly derived from the latin torques, for necklace which reflects the circular nature of the genome.

Morphology

Virions isometric (icosahedral), not enveloped, 19-27 nm in diameter.

Genome

Monopartite circular single-stranded DNA of 3.4 kb.

Genus Genomic Organization

There are two major overlapping ORFs encoding a replication-associated protein and a (larger) coat protein. Additional potential ORFs have been identified.

Type Member Genomic Organization

There are two major overlapping ORFs: the largest (ORF1) encodes a 85 kDa coat protein and the other (ORF2) a 10 kDa replication-associated protein. Two additional putative ORFs of 19 and 8 kDa have been identified.
