Archaeal GPN-loop GTPases involve a lock-switch-rock mechanism for GTP hydrolysis

mBio, 2023
Three GPN-loop GTPases, GPN1–GPN3, are central to the maturation and trafficking of eukaryotic RNA polymerase II. This GTPase family is widely represented in archaea but typically occurs as single paralogs.

Ultrastructural Characteristics of Sulfolobus acidocaldarius [PDF]

Microbiology, 1982
Summary: Isolates of Sulfolobus acidocaldarius from thermal areas in the United States and New Zealand were examined. Cell shape was growth phase-dependent and pleomorphism was more characteristic of certain isolates than of others. Cells prepared for electron microscopy by means which avoided centrifugation exhibited the lobate structure typical of ...

Biological Membranes in Extreme Conditions: Simulations of Anionic Archaeal Tetraether Lipid Membranes. [PDF]

PLoS ONE, 2016
In contrast to the majority of organisms that have cells bound by di-ester phospholipids, archaeal membranes consist of di- and tetraether phospholipids.

Electron cryo-microscopy reveals the structure of the archaeal thread filament

Nature Communications, 2022
Pili are filamentous appendages on the surface of bacteria and archaea, and play roles in multiple processes such as adhesion, motility and horizontal gene transfer. Here, Gaines et al. describe the structure of a new type of pilus, termed ‘thread’, from

DNA-Interacting Characteristics of the Archaeal Rudiviral Protein SIRV2_Gp1 [PDF]

, 2016
Whereas the infection cycles of many bacterial and eukaryotic viruses have been characterized in detail, those of archaeal viruses remain largely unexplored.

Species-Specific Recognition of Sulfolobales Mediated by UV-Inducible Pili and S-Layer Glycosylation Patterns

mBio, 2020
The UV-inducible pili system of Sulfolobales (Ups) mediates the formation of species-specific cellular aggregates. Within these aggregates, cells exchange DNA to repair DNA double-strand breaks via homologous recombination. Substitution of the Sulfolobus

Identification of a system required for the functional surface localization of sugar binding proteins with class III signal peptides in Sulfolobus solfataricus [PDF]

, 2007
The hyperthermophilic archaeon Sulfolobus solfataricus contains an unusual large number of sugar binding proteins that are synthesized as precursors with a class III signal peptide.
