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 ...

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,

Utilization of formic acid by extremely thermoacidophilic archaea species [PDF]

Microbial Biotechnology
The exploration of novel hosts with the ability to assimilate formic acid, a C1 substrate that can be produced from renewable electrons and CO2, is of great relevance for developing novel and sustainable biomanufacturing platforms.

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).

Regulation of DNA Topology in Archaea: State of the Art and Perspectives. [PDF]

Mol Microbiol
DNA topoisomerases are ubiquitous enzymes that play a crucial role in regulating DNA supercoiling which affects fundamental biological processes involving DNA. In this review, we summarize the current understanding of regulation of supercoiling by DNA topoisomerases in the third domain of life, the Archaea, with a particular focus on three key model ...

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

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.

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
