Characterization of the ATPase FlaI of the motor complex of the Pyrococcus furiosus archaellum and its interactions between the ATP-binding protein FlaH [PDF]
PeerJ, 2018 The archaellum, the rotating motility structure of archaea, is best studied in the crenarchaeon Sulfolobus acidocaldarius. To better understand how assembly and rotation of this structure is driven, two ATP-binding proteins, FlaI and FlaH of the motor ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells
FEBS Letters, Volume 599, Issue 24, Page 3569-3590, December 2025.Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

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 respiratory system of Sulfolobus acidocaldarius, a thermoacidophilic archaebacterium [PDF]
FEBS Letters, 1985 The respiratory properties, cellular ATP content and absorption difference spectra of Sulfolobus acidocaldarius (DSM 639) have been investigated. In contrast to earlier postulates regarding Thermoplasma acidophilum [(1984) Syst. Appl. Microbiol. 5, 30‐40], S. acidocaldarius seemed to depend energetically on respiration‐coupled phosphorylation.

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 ...

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 ...

Extremely Thermophilic Acidophilic Bacteria Convergent with Sulfolobus Acidocaldarius [PDF]
Journal of General Microbiology, 1975 A series of extremely thermophilic acidophilic bacteria has been characterized as closely resembling the species Sulfolobus acidocaldarius except for a totally different guanosine-cytosine content in the DNA; some conceptual consequences of this situation are discussed. Both organisms also share special features, including a very characteristic type of

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 ...
