Genes for Membrane Transport Proteins: Not So Rare in Viruses

Viruses, 2018
Some viruses have genes encoding proteins with membrane transport functions. It is unknown if these types of proteins are rare or are common in viruses.

Transition metals and oxidation reactions trigger stargate opening during the initial stages of the replicative cycle of the giant Tupanvirus

mBio
Tupanviruses, members of the family Mimiviridae, infect phagocytic cells. Particle uncoating begins inside the phagosome, with capsid opening via the stargate. The mechanism through which this opening takes place is unknown.

"Megavirales", a proposed new order for eukaryotic nucleocytoplasmic large DNA viruses

, 2013
The nucleocytoplasmic large DNA viruses (NCLDVs) comprise a monophyletic group of viruses that infect animals and diverse unicellular eukaryotes. The NCLDV group includes the families Poxviridae, Asfarviridae, Iridoviridae, Ascoviridae, Phycodnaviridae ...

Ubiquitous giants: a plethora of giant viruses found in Brazil and Antarctica

Virology Journal, 2018
Background Since the discovery of giant viruses infecting amoebae in 2003, many dogmas of virology have been revised and the search for these viruses has been intensified.

A Brazilian Marseillevirus Is the Founding Member of a Lineage in Family Marseilleviridae

Viruses, 2016
In 2003, Acanthamoeba polyphaga mimivirus (APMV) was discovered as parasitizing Acanthamoeba. It was revealed to exhibit remarkable features, especially odd genomic characteristics, and founded viral family Mimiviridae.

The virion of Cafeteria roenbergensis virus (CroV) contains a complex suite of proteins for transcription and DNA repair

, 2014
Cafeteria roenbergensis virus (CroV) is a giant virus of the Mimiviridae family that infects the marine phagotrophic flagellate C. roenbergensis. CroV possesses a DNA genome of ~730 kilobase pairs that is predicted to encode 544 proteins. We analyzed the
