Metabolism of Pentose Sugars in the Hyperthermophilic Archaea Sulfolobus solfataricus and Sulfolobus acidocaldarius [PDF]

Journal of Biological Chemistry, 2010
We have previously shown that the hyperthermophilic archaeon, Sulfolobus solfataricus, catabolizes d-glucose and d-galactose to pyruvate and glyceraldehyde via a non-phosphorylative version of the Entner-Doudoroff pathway. At each step, one enzyme is active with both C6 epimers, leading to a metabolically promiscuous pathway.

Dinucleoside Polyphosphates in Cellular Signaling: Function and Evolution Across Life

BioEssays, Volume 47, Issue 10, October 2025.
Although discovered more than 50 years ago, the cellular functions of Ap4A and related dinucleotides remain largely enigmatic. To address this knowledge gap, we organized a conference showcasing recent research that highlights the critical role of Ap4A as a global regulator across all domains of life.

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

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
Nucleoid organization in Crenarchaeota involves diverse small DNA‐binding proteins. The Lrs14‐type protein AbfR1 from Metallosphaera sedula binds nonsequence specifically across the genome and induces DNA condensation. These findings suggest a structural role for AbfR1Ms in chromatin architecture, functionally resembling bacterial nucleoid‐associated ...

Hot and crispy : CRISPR-Cas systems in the hyperthermophile Sulfolobus solfataricus [PDF]

, 2013
The CRISPR (clustered regularly interspaced short palindromic repeats) and Cas (CRISPR-associated) genes are widely spread in bacteria and archaea, representing an intracellular defence system against invading viruses and plasmids.

Characterisation of a Self‐Sufficient Cytochrome P450 Enzyme From the Bacterium Thermosporothrix hazakensis and Its Conversion Into a Peroxygenase

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
A cytochrome P450 enzyme from the thermophile Thermosporothrix hazakensis was characterised. We modified the heme domain of the enzyme through protein engineering to enable it to function as a peroxygenase biocatalyst. We demonstrated the oxidation of fatty acids and aromatic compounds and identified the metabolites.

An Unexpected Facet of Extremophiles: Their Aesthetic Potential in Artistic Expression

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
In an era marked by environmental challenges and the proliferation of misinformation, the fusion of art and science is a strategy to promote public understanding and appreciation of complex scientific phenomena. We illustrate how the use of extremophiles offers novel avenues for artistic exploration and emphasise the benefits of such interdisciplinary ...

Microbial diversity and function in the rhizosphere microbiome: Driving forces and monitoring approaches

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract As an ecological unit, the rhizosphere microbiome preserves an enormous and largely unexplored diversity of microbes that play essential roles in plant health and soil functions. Omics technologies encompassing high‐throughput approaches such as metagenomics, metatranscriptomics, and metaproteomics provide helpful tools to unravel the ...

Purification of glycerol dialkyl nonitol tetraether from Sulfolobus acidocaldarius.

Journal of Lipid Research, 1989
A modified procedure for extraction and purification of hydrolyzed archaebacterial lipids is described. Lipids were extracted from Sulfolobus acidocaldarius using a Soxhlet extraction procedure followed by trichloroacetic acid solvent-extraction of the ...

Characterization of RNAse J in Sulfolobus acidocaldarius

, 2012
In Archaea the exosome is a 3´-to- 5´ RNA processing and degaradation ma-chinery. However, recent studies identified a 5´-to- 3´ exoribonuclease termed Sso-RNAse J in the crenarchaeum Sulfolobus solfataricus (Sso). Here, we characterized a Sso-RNase J orthologue in Sulfolobus acidocaldarius (SacI-RNase J), which comprises typical signature motifs of ...
