Mollivirus sibericum

Mollivirus sibericum is a giant virus discovered in 2015 by French researchers Chantal Abergel and Jean-Michel Claverie in a 30,000-year-old sample of Siberian permafrost, where the team had previously found the unrelated giant virus Alphapithovirus sibericum . Mollivirus sibericum is a spherical DNA virus with a diameter of 500–600 nanometers (0.5–0.6 μm). [1] [2]

Mollivirus sibericum is the fourth ancient virus that scientists have found frozen in permafrost since 2003. [3] It has a sister taxon, Mollivirus kamchatka . [4]

Description

Mollivirus sibericum is an approximately spherical virion 0.6 μm in diameter. It encloses a 651 kb GC-rich genome encoding 523 proteins, of which 64% are open reading frames. [1] [5] The host's ribosomal proteins are packaged in the virion. [1]
