Organic Lake virophage
Virus classification
Group:	Group I (dsDNA)
Order:	Unassigned
Family:	Unassigned
Genus:	Unassigned
Species:	Organic Lake virophage

Organic Lake virophage is a double stranded DNA virophage (a virus that requires the presence of another virus to replicate itself and in so doing limits the other viruses ability to replicate). It was isolated from Organic Lake, Antarctica.^[1]

Virology

The virus appears to be ~100 nanometers in diameter and to be enveloped.

The genome is double stranded DNA and is 26,421 base pairs in length.

It encodes 38 proteins. These include the major coat protein, a DNA packaging ATPase, a putative DNA polymerase/primase and a N6 adenine specific DNA methyltransferase.
