A dynamic field of study has emerged involving long-range electron transport by
extracellular filaments in anaerobic bacteria, with Geobacter sulfurreducens being used as a …

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 …

Membrane proteins perform a host of vital cellular functions. Deciphering the molecular
mechanisms whereby they fulfill these functions requires detailed biophysical and structural …

Flagellar-driven motility grants unicellular organisms the ability to gather more food and
avoid predators, but the energetic costs of construction and operation of flagella are …

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

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 …

Cells from all three domains of life on Earth utilize motile macromolecular devices that
protrude from the cell surface to generate forces that allow them to swim through fluid media …

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 …
