The paper presents a cryoEM structure of the archaeal adhesive pilus (Aap) from Sulfolobus acidocaldarius, revealing three distinct conformations of the subunit AapB.

This study shows that Sulfolobus acidocaldarius uses retractable adhesion pili for twitching motility without a PilT ATPase, suggesting an ancestral bifunctional ATPase in LUCA.

This paper investigates the structural dynamics of archaeal GPN-loop GTPases, revealing a lock-switch-rock mechanism for GTP hydrolysis and its functional impact on archaeal motility.

This study identifies PRC domain proteins as essential components of the FtsZ-based cell division machinery in archaea, showing they form complexes with SepF and FtsZ and are required for proper cell division.

This study shows that type IV pili in Haloferax volcanii are essential for biofilm stability under flow, with PilA2 sufficient for normal biofilm structure.

The paper identifies and characterizes the structure of archaeal thread filaments, revealing their stabilization through glycosylation, donor strand complementation, and isopeptide bonds.

This study compares membrane permeability between archaeal and bacterial lipids using vesicles and finds that archaeal diether lipids are more permeable than bacterial diester lipids.

This study shows that autophosphorylation of ArlH inhibits its oligomerization and interaction with ArlI, essential for archaellum function and motility.

This paper characterizes SaTTM, an archaeal CYTH protein, showing it functions as a triphosphatase rather than an adenylyl cyclase, with structural and biochemical insights into its mechanism.

This paper identifies and characterizes Agl24, an archaeal enzyme involved in N-glycan chitobiose core biosynthesis, supporting the hypothesis of an archaeal origin of eukaryotic N-glycosylation.

This study presents a membrane-permeabilized ghost system for Haloferax volcanii to investigate archaellum motility, revealing ATP selectivity, negative cooperativity, and a torque-speed curve with characteristics of both bacterial flagellar motors and F1-ATPase.

This study identifies SepF as a critical component of the divisome in Haloferax volcanii, showing its role in recruiting FtsZ2 to the FtsZ1 ring during cell division.

The paper uses electron cryo-tomography and fluorescence microscopy to study cell-cell bridges in Haloferax volcanii, revealing a continuous cytoplasm and S-layer enveloping the bridges.

The paper reports 3.4 Gyr-old microfossils with appendages suggesting active motility, challenging previous assumptions about early life movement capabilities.

The paper identifies ArlCDE as the archaeal switch complex that mediates chemotaxis signal transduction to the archaellum in Haloferax volcanii.

This study identifies the function of MinD proteins in archaea, showing they oscillate and position motility machinery at cell poles, unlike their bacterial counterparts.

This study identifies species-specific regions in Sulfolobus pilin subunits and unique N-glycan patterns that mediate species-specific aggregation and DNA exchange.
