New components of the community-based DNA-repair mechanism in Sulfolobales [PDF]

MicroLife
After exposure to ultraviolet (UV) light, Sulfolobus acidocaldarius cells aggregate in a species-specific manner to exchange DNA and repair double-strand breaks via homologous recombination. The formation of cell–cell interactions is mediated by Ups pili.

Species-Specific Recognition of Sulfolobales Mediated by UV-Inducible Pili and S-Layer Glycosylation Patterns

mBio, 2020
The UV-inducible pili system of Sulfolobales (Ups) mediates the formation of species-specific cellular aggregates. Within these aggregates, cells exchange DNA to repair DNA double-strand breaks via homologous recombination. Substitution of the Sulfolobus

Enzymes Catalyzing Crotonyl-CoA Conversion to Acetoacetyl-CoA During the Autotrophic CO2 Fixation in Metallosphaera sedula

Frontiers in Microbiology, 2020
Autotrophic Crenarchaeota use two different cycles for carbon dioxide fixation. Members of the Sulfolobales use the 3-hydroxypropionate/4-hydroxybutyrate (HP/HB) cycle, whereas Desulfurococcales and Thermoproteales use the dicarboxylate/4-hydroxybutyrate

CRISPR-Cas Adaptive Immune Systems of the Sulfolobales: Unravelling Their Complexity and Diversity [PDF]

Life, 2015
The Sulfolobales have provided good model organisms for studying CRISPR-Cas systems of the crenarchaeal kingdom of the archaea. These organisms are infected by a wide range of exceptional archaea-specific viruses and conjugative plasmids, and their ...

Microbial iron cycling in acidic geothermal springs of Yellowstone National Park: Integrating molecular surveys, geochemical processes and isolation of novel Fe-active microorganisms

Frontiers in Microbiology, 2012
Geochemical, molecular, and physiological analyses of microbial isolates were combined to study the geomicrobiology of acidic iron oxide mats in Yellowstone National Park (YNP).

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.

Capturing chromosome conformation in Crenarchaea. [PDF]

Mol Microbiol
To fit into cells, chromosomes must be folded. Here we describe how members of the Archaea effect this folding process and how chromosome architecture both influences and is influenced by gene expression. Abstract While there is a considerable body of knowledge regarding the molecular and structural biology and biochemistry of archaeal information ...

The Lrs14 family of DNA-binding proteins as nucleoid-associated proteins in the Crenarchaeal order Sulfolobales. [PDF]

Mol Microbiol
Crenarchaeal Sulfolobales organize their genome with small, abundant nucleoid‐associated proteins. Here, we shed light on the distinct function of the Lrs14 family of aspecific DNA‐binding proteins, position these members toward the “chromatin organizing” side of the spectrum of DNA binders and propose a regulatory role for Lrs14s in global gene ...

DNA-Binding Properties of a Novel Crenarchaeal Chromatin-Organizing Protein in Sulfolobus acidocaldarius

Biomolecules, 2022
In archaeal microorganisms, the compaction and organization of the chromosome into a dynamic but condensed structure is mediated by diverse chromatin-organizing proteins in a lineage-specific manner. While many archaea employ eukaryotic-type histones for
