Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 10, Page 1644-1657, October 2026.ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

Assembly of complex viruses exemplified by a halophilic euryarchaeal virus
Nature Communications, 2019 Here, the authors present the cryo-EM structure of the archaeal virus SH1 at 3.8 Å resolution and show how the major capsid proteins assemble into hetero-hexamers, providing insights into the assembly process of this and related PRD1-adeno lineage ...

A new example of viral intein in Mimivirus
Virology Journal, 2005 Background Inteins are "protein introns" that remove themselves from their host proteins through an autocatalytic protein-splicing. After their discovery, inteins have been quickly identified in all domains of life, but only once to date in the genome of

Environmental Microbiology, Volume 28, Issue 10, October 2026.The largetooth sawfish skin supports a distinct microbiome enriched in anaerobic metabolic and dormancy potential, consistent with microbial persistence under low‐oxygen conditions. Greater among‐individual taxonomic variability coupled with functional redundancy potential supports a lottery‐like mechanism of microbiome assembly.

The structures of two archaeal type IV pili illuminate evolutionary relationships
, 2020 International audienceWe have determined the cryo-electron microscopic (cryo-EM) structures of two archaeal type IV pili (T4P), from Pyrobaculum arsenaticum and Saccharolobus solfataricus, at 3.8 Å and 3.4 Å resolution, respectively.

Environmental Microbiology, Volume 28, Issue 10, October 2026.At 35 days posthatching, the gut microbiome of juvenile chum salmon (Oncorhynchus keta) encodes complete biosynthetic pathways for essential amino acids (threonine, leucine, valine/isoleucine and lysine) and B‐vitamins (thiamine, riboflavin and biotin) that are absent or incomplete in the host genome. Bacterial taxa, including Bartonella, Acinetobacter

Archaeal virus-host interactions
The work presented in this thesis provides novel insights in several aspects of the molecular biology of archaea, bacteria and their viruses. Three fundamentally different groups of viruses are associated with the three domains of life. Archaeal viruses are characterized by a particularly high morphological and genetic diversity. Some archaeal viruses,

mSystemsAlthough viruses have been shown to infect all domains of life, our understanding of the genetic program behind the exploitation of host resources to produce progeny virions is thus far limited to several bacterial viruses.
