Acta Biochimica et Biophysica Sinica, 2022 Apurinic/apyrimidic (AP) sites are severe DNA damages and strongly block DNA extension by major DNA polymerases. Y-family DNA polymerases possess a strong ability to bypass AP sites and continue the DNA synthesis reaction, which is called translesion ...

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea
The FEBS Journal, EarlyView.S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

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 ...

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes
Advanced NanoBiomed Research, Volume 6, Issue 6, June 2026.Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

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 ...

Optimization of Enzymatic Gas-Phase Reactions by Increasing the Long-Term Stability of the Catalyst [PDF]
, 2004 Enzymatic gas-phase reactions are usually performed in continuous reactors, and thus very stable and active catalysts are required to perform such transformations on cost-effective levels.

The Sulfolobus solfataricus P2 genome project
FEBS Letters, 1996 Over 800 kbp of the 3‐Mbp genome of Sulfolobus solfataricus have been sequenced to date. Our approach is to sequence subclones of mapped cosmids, followed by sequencing directly on cosmid templates with custom primers. Using a prototype automated system for genome‐scale analysis, known as MAGPIE, along with other tools, we have discovered one open ...

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

Protein phosphorylation in the Archaebacterium Sulfolobus acidocaldarius [PDF]
European Journal of Biochemistry, 1984 A number of proteins of the sulphur-dependent archaebacterium Sulfolobus acidocaldarius are phosphorylated in vivo. The extent of phosphorylation depends on the state of growth and is most intense in the late exponential phase. Some of the phosphorylated proteins are strongly associated with the bacterial membrane.
