Motility often plays a decisive role in the survival of species. Five systems of motility have
been studied in depth: those propelled by bacterial flagella, eukaryotic actin polymerization …

Each of the three domains of life exhibits a unique motility structure: while Bacteria use
flagella, Eukarya employ cilia, and Archaea swim using archaella. Since the new name for …

Echoing the repeated convergent evolution of flight and vision in large eukaryotes,
propulsive swimming motility has evolved independently in microbes in each of the three …

Archaea use a molecular machine, called the archaellum, to swim. The archaellum consists
of an ATP-powered intracellular motor that drives the rotation of an extracellular filament …

Many surface structures in archaea including various types of pili and the archaellum
(archaeal flagellum) are homologous to bacterial type IV pili systems (T4P). The T4P consist …

Archaea use flagella known as archaella—distinct both in protein composition and structure
from bacterial flagella—to drive cell motility, but the structural basis of this function is …

Motile archaea swim using a rotary filament, the archaellum, a surface appendage that
resembles bacterial flagella structurally, but is homologous to bacterial type IV pili. Little is …

The archaellum is the macromolecular machinery that Archaea use for propulsion or surface
adhesion, enabling them to proliferate and invade new territories. The molecular …

Cell surfaces are critical for diverse functions across all domains of life, from cell-cell
communication and nutrient uptake to cell stability and surface attachment. While certain …

Archaea are ubiquitously present in nature and colonize environments with broadly varying
growth conditions. Several surface appendages support their colonization of new habitats. A …
