The Effects of Temperature and Growth Phase on the Lipidomes of Sulfolobus islandicus and Sulfolobus tokodaii [PDF]

Life, 2015
The functionality of the plasma membrane is essential for all organisms. Adaption to high growth temperatures imposes challenges and Bacteria, Eukarya, and Archaea have developed several mechanisms to cope with these.

Genome Sequencing of Sulfolobus sp. A20 from Costa Rica and Comparative Analyses of the Putative Pathways of Carbon, Nitrogen, and Sulfur Metabolism in Various Sulfolobus Strains

Frontiers in Microbiology, 2016
The genome of Sulfolobus sp. A20 isolated from a hot spring in Costa Rica was sequenced. This circular genome of the strain is 2,688,317 bp in size and 34.8% in G+C content, and contains 2,591 open reading frames (ORFs). Strain A20 shares ~95.6% identity

Coordination of chromosome segregation and cell division in the archaeon Sulfolobus acidocaldarius [PDF]

Nature Communications
Despite its fundamental importance for the propagation of all cellular life, very little is known about the molecular basis of chromosome segregation in archaea.

Evolutionary conservation of ubiquitin-like protein urmylation as revealed by URM1 gene shuffle from archaea to yeast [PDF]

Communications Biology
Urm1 from yeast is a unique ubiquitin-like protein with dual functionality. It has been shown to operate in tRNA thiolation and protein urmylation, combining features typical of bacterial sulfur carriers and classical ubiquitin-like modifiers.

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

Viruses, 2017
Whereas the infection cycles of many bacterial and eukaryotic viruses have been characterized in detail, those of archaeal viruses remain largely unexplored.

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.

Electronic and Structural Heterogeneity in the Diiron Center of Sulerythrin: Insights From Hybrid QM/MM Calculations. [PDF]

Chemphyschem
QM/MM modeling of Sulerythrin (SulE) identifies three electronic states of its diiron center, differing in protonation and bridging ligands. The results reconcile crystallographic heterogeneity and reveal how subtle electronic and structural changes govern non‐heme diiron enzyme reactivity.

Chromosome conformation capture assay combined with biotin enrichment for hyperthermophilic archaea

STAR Protocols, 2021
Summary: Chromosome organization in archaea has long been enigmatic due, in part, to the typically small cell size of archaea and the extremophilic nature of many of the model archaeal species studies, rendering live-cell imaging technically challenging.
