Most prokaryotic cells are encased in a surface layer (S-layer) consisting of a paracrystalline
array of repeating lattice-forming proteins. S-layer proteins populate a vast and diverse …

Genome analysis points to N‐glycosylation as being an almost universal posttranslational
modification in Archaea. Although such predictions have been confirmed in only a limited …

The S-layer is a proteinaceous surface lattice found in the cell envelope of bacteria and
archaea. In most archaea, a glycosylated S-layer constitutes the sole cell wall and there is …

N-glycosylation is a post-translational modification of proteins that occurs across all three
domains of life. In Archaea, N-glycosylation is crucial for cell stability and motility, but …

Restriction–modification (RM) systems in bacteria are implicated in multiple biological roles
ranging from defense against parasitic genetic elements, to selfish addiction cassettes, and …

Hypersaline environments are the source of many viruses infecting different species of
halophilic euryarchaea. Information on infection mechanisms of archaeal viruses is scarce …

(1) Background: Haloarchaea comprise extremely halophilic organisms of the Archaea
domain. They are single-cell organisms with distinctive membrane lipids and a protein …

It is increasingly recognized that very small proteins (μ-proteins) are ubiquitously found in all
species of the three domains of life, and that they fulfill important functions. The halophilic …

In previous publications, it was hypothesized that Micrarchaeota cells are covered by two
individual membrane systems. This study proves that at least the recently cultivated …

Horizontal gene transfer is a means by which bacteria, archaea, and eukaryotes are able to
trade DNA within and between species. While there are a variety of mechanisms through …
