Megavirus [2] is a viral genus, phylogenetically related to Acanthamoeba polyphaga mimivirus (APMV). [3] In colloquial speech, Megavirus chilense is more commonly referred to as just "Megavirus". Until the discovery of pandoraviruses in 2013, it had the largest capsid diameter of all known viruses, as well as the largest and most complex genome ...
The presence of four aminoacyl tRNA synthetase encoding genes in mimivirus and mamavirus genomes, both species within the Mimiviridae family, as well as the discovery of seven aminoacyl tRNA synthetase genes in the megavirus genome (including those in Mimiviridae) provide evidence that these large DNA viruses may have evolved from a shared ...
C — Courdo11 virus group: includes Mont1, [11] Courdo7, Courdo11, Megavirus chilensis, LBA111, Powai lake megavirus and Terra1. [15] [16] The majority of Mimiviridae appear to belong to this subfamily (Mimiviruses). [10] It is sometimes also referred to as Mimiviridae group I. [17]
The mimivirus is the fourth-largest virus, after the Megavirus chilensis, Pandoravirus and Pithovirus. Mimivirus has a capsid diameter of 400 nm. Protein filaments measuring 100 nm project from the surface of the capsid, bringing the total length of the virus up to 600 nm.
Four of these species were from the pandoravirus, cedratvirus (sometimes classified as a subgroup of pithovirus), megavirus and pacmanvirus (part of Asfarviridae) families, which weren't previously revived from the permafrost. In addition, five more species from these families were found in already thawed permafrost, with no way to tell their age.
The giant viruses Mimivirus, Megavirus, and Pandoravirus infect Acanthamoeba. [25] Members of the genus Acanthamoeba are unusual in serving as hosts for a variety of giant viruses (that have more than 1000 protein-coding genes; for instance, Pandoravirus, which has about 2500 protein-coding genes in its genome).
Zamilon was discovered in 2013, in Acanthamoeba polyphaga amoebae co-infected with the giant virus Mont1, isolated from a Tunisian soil sample. [2] [3] [5] As of 2015, Zamilon is one of three virophages to have been isolated physically, the others being Sputnik and Mavirus; several other virophage DNAs have been discovered using metagenomics but have not been characterised physically.
