Tupanvirus is the name of two giant viruses, Tupanvirus deep ocean and Tupanvirus soda lake. They are named after Tupã (Tupan), a Guaraní thunder god, and the places they were found. Unique to these viruses is they can incorporate (or translate) all 20 standard amino acids.[1][2][3]
Tupanvirus measure up to 1.2 μm in complete virion length, with a capsid similar to that of amoebal mimiviruses in size (~450 nm) and structure. However, the Tupanvirus virion presents a large cylindrical tail (~550 nm × 450 nm diameter) attached to the base of the capsid.[2] Some particles can reach up to 2.3 μm because of the variation in tail size. The genome contains roughly 1.5 million base pairs of double-stranded DNA,[1] coding for 1276–1425 predicted proteins. Many genes that encode for processes found in cellular organisms are found in Tupanvirus genome. [2] They are able to infect protists and amoebas, but pose no threat to humans.[1] As a giant virus, Tupanvirus present the largest translational apparatus within the known virosphere.
