Notes on Genus: Epsilontorquevirus
Type member: Torque teno tamarin virus
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.
Virions isometric (icosahedral), not enveloped, 19-27 nm in diameter.
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.
