Discovery and Further Studies on Giant Viruses at the IHU Mediterranee Infection That Modified the Perception of the Virosphere

Viruses, 2019
The history of giant viruses began in 2003 with the identification of Acanthamoeba polyphaga mimivirus. Since then, giant viruses of amoeba enlightened an unknown part of the viral world, and every discovery and characterization of a new giant virus ...

Ancestrality and Mosaicism of Giant Viruses Supporting the Definition of the Fourth TRUC of Microbes

Frontiers in Microbiology, 2018
Giant viruses of amoebae were discovered in 2003. Since then, their diversity has greatly expanded. They were suggested to form a fourth branch of life, collectively named ‘TRUC’ (for “Things Resisting Uncompleted Classifications”) alongside Bacteria ...

Giant Viruses—Big Surprises

Viruses, 2019
Viruses are the most prevalent infectious agents, populating almost every ecosystem on earth. Most viruses carry only a handful of genes supporting their replication and the production of capsids.

Membrane assembly during the infection cycle of the giant Mimivirus. [PDF]

PLoS Pathogens, 2013
Although extensively studied, the structure, cellular origin and assembly mechanism of internal membranes during viral infection remain unclear. By combining diverse imaging techniques, including the novel Scanning-Transmission Electron Microscopy ...

Acanthamoeba polyphaga de novo transcriptome and its dynamics during Mimivirus infection

Scientific Reports
Mimivirus bradfordmassiliense (Mimivirus) is a giant virus that infects Acanthamoeba species – opportunistic human pathogens. Long- and short-read sequencing were used to generate a de novo transcriptome of the host and followed the dynamics of both host

Stem-Loop RNA Hairpins in Giant Viruses: Invading rRNA-Like Repeats and a Template Free RNA

Frontiers in Microbiology, 2018
We examine the hypothesis that de novo template-free RNAs still form spontaneously, as they did at the origins of life, invade modern genomes, contribute new genetic material.

Recombinant expression of Mimivirus L725 ORFan gene product

, 2017
International audienceMimivirus was the first discovered amoebal giant virus. The Mimivirus virions are covered by a dense layer of approximately 130 nm-long fibers, the length and shape of which diverge from those of other viruses.

Characterization of a Trifunctional Mimivirus mRNA Capping Enzyme and Crystal Structure of the RNA Triphosphatase Domain [PDF]

, 2008
SummaryThe RNA triphosphatase (RTPase) components of the mRNA capping apparatus are a bellwether of eukaryal taxonomy. Fungal and protozoal RTPases belong to the triphosphate tunnel metalloenzyme (TTM) family, exemplified by yeast Cet1. Several large DNA
