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.

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

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.

Acidianus, Sulfolobus and Metallosphaera surface layers: structure, composition and gene expression

, 2009
P>The cell walls of Sulfolobales species consist of proteinaceous S-layers assembled from two polypeptides, SlaA and SlaB. We isolated the large S-layer protein of Acidianus ambivalens and both S-layer subunits of Sulfolobus solfataricus and ...

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 ...

Host-virus Interaction Dynamics Using Sulfolobus Spindle-shaped Virus and Host Sulfolobales System

The Sulfolobus Spindle-shaped virus (SSV) is among the most studied archaeal viruses, particularly in extreme environments. This virus predominantly infects multiple Crenarchaea from the Sulfolobaceae family.

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

Terminal Oxidase Diversity and Function in “ Metallosphaera yellowstonensis ”: Gene Expression and Protein Modeling Suggest Mechanisms of Fe(II) Oxidation in the Sulfolobales

, 2011
“ Metallosphaera yellowstonensis ” is a thermoacidophilic archaeon isolated from Yellowstone National Park that is capable of autotrophic growth using Fe(II), elemental S, or pyrite as electron donors. Analysis of the draft genome
