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.

Protein kinase Sut1 from the Crenarchaeon Sulfolobus acidocaldarius displays tyrosine phosphorylation activity

bioRxiv
Protein phosphorylation is a key cellular signaling mechanism that exists in all life forms. Unlike Bacteria and Eukarya, in which protein phosphorylation has thoroughly been studied, post-translational modification by means of phosphorylation have only ...

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 ...

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.

Data_Sheet_1_Exopolysaccharide composition and size in Sulfolobus acidocaldarius biofilms.pdf

, 2022
Extracellular polymeric substances (EPS) comprise mainly carbohydrates, proteins and extracellular DNA (eDNA) in biofilms formed by the thermoacidophilic Crenarchaeon Sulfolobus acidocaldarius. However, detailed information on the carbohydrates in the S.

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 ...

Inducible and constitutive promoters for genetic systems in Sulfolobus acidocaldarius [PDF]

Extremophiles, 2010
Central to genetic work in any organism are the availability of a range of inducible and constitutive promoters. In this work we studied several promoters for use in the hyperthermophilic archaeon Sulfolobus acidocaldarius. The promoters were tested with the aid of an E. coli-Sulfolobus shuttle vector in reporter gene experiments.

The 2-D Crystalline Cell Wall of Sulfolobus acidocaldarius: Structure, Solubilization, and Reassembly

, 1980
A new type of bacteria was discovered by Brock et al. (1972) during their investigation of microorganisms living at high temperatures. They assigned the new bacteria to a hitherto unknown genus which they called Sulfolobus.

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.
