General Description

This is one of the genera in the family Anelloviridae and contains viruses from Douroucouli (owl monkey) with a genome of 3.7 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 3.7 kb.

Genus Genomic Organization

There are two major overlapping ORFs encoding a replication-associated protein and a (larger) coat protein. A possible additional ORF has also been identified.

Type Member Genomic Organization

There are two major overlapping ORFs: the largest (ORF1) encodes a 86 kDa coat protein and the other (ORF2) a 14 kDa replication-associated protein. There is also a putative ORF3 of 16 kDa (function unknown).
