Crystal structure of the translation recovery factor Trf from Sulfolobus solfataricus

FEBS Open Bio, 2020
During translation initiation, the heterotrimeric archaeal translation initiation factor 2 (aIF2) recruits the initiator tRNAi to the small ribosomal subunit.

Deficiency of the tRNATyr:Ψ35-synthase aPus7 in Archaea of the Sulfolobales order might be rescued by the H/ACA sRNA-guided machinery

Nucleic Acids Research, 2009
Up to now, Ψ formation in tRNAs was found to be catalysed by stand-alone enzymes. By computational analysis of archaeal genomes we detected putative H/ACA sRNAs, in four Sulfolobales species and in Aeropyrum pernix, that might guide Ψ35 formation in pre ...

Tetraether archaeal lipids promote long‐term survival in extreme conditions

Molecular Microbiology, Volume 121, Issue 5, Page 882-894, May 2024.
Unique archaeal lipid membrane composition, including membrane‐spanning, tetraether lipids, presumably contribute to survival in extreme pH, temperature, and salinity. The biosynthesis of tetraether lipids in the model species Thermococcus kodakarensis promotes survival at high temperatures, and we demonstrate that alternative lipid species are ...

Aerobic lineage of the oxidative stress response protein rubrerythrin emerged in an ancient microaerobic, (hyper)thermophilic environment

Frontiers in Microbiology, 2016
Rubrerythrins (RBRs) are non-heme di-iron proteins belonging to the ferritin-like superfamily (FLSF). They are involved in oxidative stress defense as peroxide scavengers in a wide range of organisms.

Rational design of unrestricted pRN1 derivatives and their application in the construction of a dual plasmid vector system for Saccharolobus islandicus

mLife, Volume 3, Issue 1, Page 119-128, March 2024.
Abstract Saccharolobus islandicus REY15A represents one of the very few archaeal models with versatile genetic tools, which include efficient genome editing, gene silencing, and robust protein expression systems. However, plasmid vectors constructed for this crenarchaeon thus far are based solely on the pRN2 cryptic plasmid.

Insights Into the Chromatin Structure of Thermoplasma volcanium: Archaeal HU Regulates Alba‐Mediated DNA Compaction

Archaea, Volume 2024, Issue 1, 2024.
Archaeal species encode a diversity of chromatin proteins that play distinct roles in genome compaction. Although our understanding of the individual proteins has been growing, their contributions to higher‐order folding in the archaeal chromosome remain to be explored. In this study, we investigated the chromatin structure of Thermoplasma volcanium, a

CryoEM reveals the structure of an archaeal pilus involved in twitching motility

Nature Communications
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 species encode for three types of T4P, namely the archaellum, the UV-inducible pilus ...
