ChemPhysChem, Volume 27, Issue 2, January 2026.QM/MM modeling of Sulerythrin (SulE) identifies three electronic states of its diiron center, differing in protonation and bridging ligands. The results reconcile crystallographic heterogeneity and reveal how subtle electronic and structural changes govern non‐heme diiron enzyme reactivity.

Structure of Csx1-cOA4 complex reveals the basis of RNA decay in Type III-B CRISPR-Cas
Nature Communications, 2019 Type III CRISPR-Cas RNases from the Csm and Csx families are activated by cyclic oligoadenylates (cOA). Here the authors present the cOA bound Sulfolobus islandicus Csx1 structure, which forms a hexamer and reveal an allosteric mechanism for the ...

Cross‐Feeding of Carbon and Nitrogen Between Aquificales and Thermus in Hot Springs
Environmental Microbiology, Volume 28, Issue 1, January 2026.Pampinifervens and Thermus populations are co‐distributed in hot springs in Yellowstone and Iceland. Genome reconstruction suggests Pampinifervens Flu05 cross feeds Thermus organic carbon and nitrogen, a phenomenon that was verified via co‐culture studies.

The transcript cleavage factor paralogue TFS4 is a potent RNA polymerase inhibitor
Nature Communications, 2017 Transcript cleavage factors such as eukaryotic TFIIS assist the resumption of transcription following RNA pol II backtracking. Here the authors find that one of the Sulfolobus solfataricus TFIIS homolog—TFS4—has evolved into a potent RNA polymerase ...

Ultrastructural Characteristics of Sulfolobus acidocaldarius [PDF]
Microbiology, 1982 Summary: Isolates of Sulfolobus acidocaldarius from thermal areas in the United States and New Zealand were examined. Cell shape was growth phase-dependent and pleomorphism was more characteristic of certain isolates than of others. Cells prepared for electron microscopy by means which avoided centrifugation exhibited the lobate structure typical of ...

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 ...

Alterations of the transcriptome of Sulfolobus acidocaldarius by exoribonuclease aCPSF2.
PLoS ONE, 2013 Recent studies identified a 5´ to 3´ exoribonuclease termed Sso-RNase J in the crenarchaeon Sulfolobus solfataricus (Sso), which has been reclassified to the aCPSF2 (archaeal cleavage and polyadenylation specificity factor 2) group of β-CASP proteins. In

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 ...

RNA Biology, 2018 Sulfolobus islandicus Rey15A encodes one Type I-A and two Type III-B systems, all of which are active in mediating nucleic acids interference. However, the effectiveness of each CRISPR system against virus infection was not tested in this archaeon.
