Improvement of a Sulfolobus-E. coli Shuttle Vector for Heterologous Gene Expression in Sulfolobus acidocaldarius

open access: yesJournal of Microbiology and Biotechnology, 2015
A Sulfolobus-E. coli shuttle vector for an efficient expression of the target gene in S. acidocaldarius strain was constructed. The plasmid-based vector pSM21 and its derivative pSM21N were generated based on the pUC18 and Sulfolobus cryptic plasmid pRN1. They carried the S.

Characterization of a hyperthermophilic sulphur-oxidizing biofilm produced by archaea isolated from a hot spring

open access: yesElectronic Journal of Biotechnology, 2017
Background: Sulphur-oxidizing microorganisms are widely used in the biofiltration of total reduced sulphur compounds (odorous and neurotoxic) produced by industries such as the cellulose and petrochemical industries, which include high-temperature ...

Structural basis for inhibition of an archaeal CRISPR–Cas type I-D large subunit by an anti-CRISPR protein

open access: yesNature Communications, 2020
In type I-D CRISPR–Cas systems, the nuclease and helicase activities are carried out by separate subunits. The crystal structure of Sulfolobus islandicus type I-D large subunit Cas10d, containing a nuclease domain, reveals unusual architecture.

Designing Enzymatic Reactivity with an Expanded Palette

open access: yesChemBioChem, Volume 26, Issue 11, June 3, 2025.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...

A study on the correlation of nucleotide skews and the positioning of the origin of replication: different modes of replication in bacterial species [PDF]

open access: yes, 2005
Deviations from Chargaff's 2nd parity rule, according to which A∼T and G∼C in single stranded DNA, have been associated with replication as well as with transcription in prokaryotes. Based on observations regarding mainly the transcription-replication co-

Transcriptome changes in STSV2‐infected Sulfolobus islandicus REY15A undergoing continuous CRISPR spacer acquisition

open access: yesMolecular Microbiology, 2016
A transcriptome study was performed on Sulfolobus islandicus REY15A actively undergoing CRISPR spacer acquisition from the crenarchaeal monocaudavirus STSV2 in rich and basal media over a 6 day period.

Engineering and Structural Elucidation of a Sac7d‐Derived IgG Fc‐Specific Affitin and Its Application for the Light‐Controlled Affinity Purification of Antibodies

open access: yesChemBioChem, Volume 26, Issue 11, June 3, 2025.
An affitin derived from the Sac7d scaffold enables the light‐controlled affinity purification of antibodies under physiological conditions, thus overcoming limitations of protein A chromatography. X‐ray crystallographic analysis and affinity measurements reveal complex formation with Fc at the CH2/CH3 junction, similar to protein A/G and FnRn. Combined

DNA Binding in High Salt: Analysing the Salt Dependence of Replication Protein A3 from the Halophile Haloferax volcanii [PDF]

open access: yes, 2012
Halophilic archaea maintain intracellular salt concentrations close to saturation to survive in high-salt environments and their cellular processes have adapted to function under these conditions.

AcrDB update: Predicted 3D structures of anti‐CRISPRs in human gut viromes

open access: yesProtein Science, Volume 34, Issue 6, June 2025.
Abstract Anti‐CRISPR (Acr) proteins play a key role in phage‐host interactions and hold great promise for advancing genome‐editing technologies. However, finding new Acrs has been challenging due to their low sequence similarity. Recent advances in protein structure prediction have opened new pathways for Acr discovery by using 3D structure similarity.

Endogenous Mutagenesis in Recombinant Sulfolobus Plasmids [PDF]

open access: yesJournal of Bacteriology, 2013
ABSTRACT Low rates of replication errors in chromosomal genes of Sulfolobus spp. demonstrate that these extreme thermoacidophiles can maintain genome integrity in environments with high temperature and low pH. In contrast to this genetic stability, we observed unusually frequent mutation of the β-
