Cytochromes b5 Occurrence in Viruses Belonging to the Order Megavirales
Research SquareCytochrome b5 is a small electron transport protein that is found in animals, plants, fungi and photosynthetic proteobacteria where it plays key metabolic roles in energy production, lipid and sterol biosynthesis and cytochrome P450 biochemistry ...

Zamilon, a novel virophage with Mimiviridae host specificity. [PDF]
PLoS ONE, 2014 Virophages, which are potentially important ecological regulators, have been discovered in association with members of the order Megavirales. Sputnik virophages target the Mimiviridae, Mavirus was identified with the Cafeteria roenbergensis virus, and ...

A Large Open Pangenome and a Small Core Genome for Giant Pandoraviruses [PDF]
Frontiers in Microbiology, 2018 Giant viruses of amoebae are distinct from classical viruses by the giant size of their virions and genomes. Pandoraviruses are the record holders in size of genomes and number of predicted genes. Three strains, P. salinus, P. dulcis, and P.

The Double-Stranded DNA Virosphere as a Modular Hierarchical Network of Gene Sharing [PDF]
mBio, 2016 Virus genomes are prone to extensive gene loss, gain, and exchange and share no universal genes. Therefore, in a broad-scale study of virus evolution, gene and genome network analyses can complement traditional phylogenetics.

The common ancestor of archaea and eukarya was not an archaeon. [PDF]
Archaea, 2013 It is often assumed that eukarya originated from archaea. This view has been recently supported by phylogenetic analyses in which eukarya are nested within archaea. Here, I argue that these analyses are not reliable, and I critically discuss archaeal ancestor scenarios, as well as fusion scenarios for the origin of eukaryotes.

New Brazilian giant viruses isolation from environmental samples using a panel of protozoa.
Frontiers in Microbiology, 2015 The Megavirales are a newly described order capable of infecting different types of eukaryotic hosts. For the most part, the natural host is unknown.
