Ixotrophy is a contact-dependent predatory strategy of filamentous bacteria in aquatic
environments for which the molecular mechanism remains unknown. We show that predator …

The swimming device of archaea—the archaellum—presents asparagine (N)-linked
glycans. While N-glycosylation serves numerous roles in archaea, including enabling their …

Amongst the major types of archaeal filaments, several have been shown to closely
resemble bacterial homologues of the Type IV pili (T4P). Within Sulfolobales, member …

Archaeal viruses display a high degree of structural and genomic diversity. Few details are
known about the mechanisms by which these viruses enter and exit their host cells …

ABSTRACT A type II VapB14 antitoxin regulates biofilm dispersal in the archaeal
thermoacidophile Sulfolobus acidocaldarius through traditional toxin neutralization but also …

The DPANN archaeal clade includes obligately ectosymbiotic species. Their cell surfaces
potentially play an important role in the symbiotic interaction between the ectosymbionts and …

Type 1 pili are important virulence factors of uropathogenic Escherichia coli that mediate
bacterial attachment to epithelial cells in the urinary tract. The pilus rod is comprised of …

Archaea produce various protein filaments with specialised functions. While some archaea
produce only one type of filament, the archaeal model species Sulfolobus acidocaldarius …

Bacteriophage tail fibers (or called tail spikes) play a critical role in the early stage of
infection by binding to the bacterial surface. Podophages with known structures usually …

Type IV pili are filamentous appendages found in most bacteria and archaea, where they
can support functions such as surface adhesion, DNA uptake, aggregation, and motility. In …
