  • Metabolic arsenal of giant viruses: Host hijack or self-use?
    Although giant viruses are not able to replicate autonomously and still require a host for their multiplication, numerous metabolic genes involved in energy production have been recently detected in giant virus genomes from many environments
  • Viruses don’t have a metabolism, but some have the building blocks for . . .
    Researchers have discovered genes for key cellular metabolic cycles in many giant viruses, suggesting that these microbes may be interacting with their hosts — and affecting the environment — in more diverse ways than previously thought Image courtesy of Chuan Xiao and Yuejiao Xian, University of Texas at El Paso
  • Giant Viruses: Blurring the Line Between Life and Non-Life
    For instance, some giant viruses contain genes for tRNA synthetases, which are critical for protein synthesis—a capability rarely seen in viruses This semi-autonomous behavior challenges the notion that viruses are entirely dependent entities
  • The Astounding World of Glycans from Giant Viruses
    These viral genes include those that encode the production of activated sugars, glycosyltransferases, and other enzymes able to manipulate sugars at various levels This review focuses on large and giant viruses that produce carbohydrate-processing enzymes
  • Giant Viruses Carry Genetic Code That May Control The Metabolism of . . .
    In addition to finding expected genes for processes such as capsid construction and viral infectivity, the team found giant viruses harbour a huge diversity of genes involved in aspects of cellular metabolism, including processes such as nutrient uptake, light harvesting, and nitrogen metabolism
  • The Autonomous Glycosylation of Large DNA Viruses - PMC
    In recent years, a newly discovered group of eukaryotic viruses, belonging to the Nucleo-Cytoplasmic Large DNA Virus (NCLDV) group, was shown to have several features that are typical of cellular organisms, including the presence of components of the glycosylation machinery
  • 20 years of research on giant viruses | npj Viruses - Nature
    Some twenty years ago, the discovery of the first giant virus, Acanthamoeba polyphaga mimivirus (now mimivirus bradfordmassiliense species), paved the way for the discovery of more than 10 new
  • Giant viruses: The difficult breaking of multiple epistemological . . .
    In this article, we examine to what extent the giant viruses challenge previous definitions of viruses, the diversity of forms they could take, and how they might have evolved from extinct ancestral cellular lineages
