Stay or Go: Sulfolobales Biofilm Dispersal Is Dependent on a Bifunctional VapB Antitoxin [PDF]

MBio, 2023
A type II VapB14 antitoxin regulates biofilm dispersal in the archaeal thermoacidophile Sulfolobus acidocaldarius through traditional toxin neutralization but also through noncanonical transcriptional regulation.

Physiology, Taxonomy, and Sulfur Metabolism of the Sulfolobales, an Order of Thermoacidophilic Archaea

Frontiers in Microbiology, 2021
The order Sulfolobales (phylum Crenarchaeota) is a group of thermoacidophilic archaea. The first member of the Sulfolobales was discovered in 1972, and current 23 species are validly named under the International Code of Nomenclature of Prokaryotes.

An Lrs14 family protein functions as a nucleoid-associated protein regulating cell cycle progression in Sulfolobales [PDF]

Communications Biology
Archaea of the order Sulfolobales possess eukaryotic-like cell cycle. The chromatin organization in these archaea is supposed to rely on nucleoid-associated proteins (NAPs).

Identification of novel components of the Ced and Ups systems in Saccharolobus islandicus REY15A [PDF]

mLife
In Sulfolobales cells, transcription of the Ups (UV‐inducible pili of Sulfolobus) and Ced (Crenarchaeal system for exchange of DNA) genes is highly induced by DNA damage, and the two systems play key roles in pili‐mediated cell aggregation and ...

Heavily Armed Ancestors: CRISPR Immunity and Applications in Archaea with a Comparative Analysis of CRISPR Types in Sulfolobales

Biomolecules, 2020
Prokaryotes are constantly coping with attacks by viruses in their natural environments and therefore have evolved an impressive array of defense systems.

Structural Stability Comparisons Between Natural and Engineered Group II Chaperonins: Are Crenarchaeal “Heat Shock” Proteins Also “pH Shock” Resistant? [PDF]

Microorganisms
Archaeal group II chaperonins, also known as heat shock proteins (HSPs), are abundantly expressed in Sulfolobales. HSPα and HSPβ gene expression is upregulated during thermal shock. HSPs form large 18-mer complexes that assist in folding nascent proteins

Cran1, member of a new class of OLD family ATPases, functions in cell cycle progression in an archaeon [PDF]

EMBO Reports
Overcoming lysogenization defect (OLD) proteins are diverse ATPase-nucleases functioning in antiphage defense in bacteria. However, the role of these proteins in archaea is currently unknown.

The Lrs14‐Like AbfR1 Homolog From Metallosphaera sedula Is a Nucleoid‐Organizing Protein [PDF]

MicrobiologyOpen
Nucleoid organization in Crenarchaeota is mediated by a plethora of diverse families of small DNA‐binding proteins. However, the role of the Lrs14 family, a prevalent family of small DNA‐binding proteins within the Crenarchaeal order of the Sulfolobales,

Towards a molecular picture of the archaeal cell surface [PDF]

Nature Communications
Archaea produce various protein filaments with specialised functions. While some archaea produce only one type of filament, the archaeal model species Sulfolobus acidocaldarius generates four.

Trace gas oxidation sustains energy needs of a thermophilic archaeon at suboptimal temperatures [PDF]

Nature Communications
Diverse aerobic bacteria use atmospheric hydrogen (H2) and carbon monoxide (CO) as energy sources to support growth and survival. Such trace gas oxidation is recognised as a globally significant process that serves as the main sink in the biogeochemical ...
