Acquisition of elemental sulfur by sulfur‐oxidising Sulfolobales

Environmental Microbiology, Volume 26, Issue 9, September 2024.
The distribution of sulfur oxidoreductase (SOR) homologues is patchy among Sulfolobales. Herein, physiological and ecological consequences of encoding SOR were investigated. While non‐SOR‐encoding strains required direct contact with S80 for oxidation, SOR‐encoding strains oxidised it without direct contact via hydrogen sulfide (H2S)‐promoted formation

Differences in the composition of archaeal communities in sediments from contrasting zones of Lake Taihu

Frontiers in Microbiology, 2016
In shallow lakes, different primary producers might impact the physiochemical characteristics of the sediment and the associated microbial communities.

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 ...

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.

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.

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 ...

An ancient family of SelB elongation factor-like proteins with a broad but disjunct distribution across archaea

BMC Evolutionary Biology, 2011
Background SelB is the dedicated elongation factor for delivery of selenocysteinyl-tRNA to the ribosome. In archaea, only a subset of methanogens utilizes selenocysteine and encodes archaeal SelB (aSelB).

Cell Structure Changes in the Hyperthermophilic Crenarchaeon Sulfolobus islandicus Lacking the S-Layer

mBio, 2019
Rediscovery of the ancient evolutionary relationship between archaea and eukaryotes has revitalized interest in archaeal cell biology. Key to the understanding of archaeal cells is the surface layer (S-layer), which is commonly found in Archaea but whose
