STAR Protocols, 2021 Summary: Type III CRISPR-cas systems initiate cyclic oligo-adenylate (cOA) signaling to initiate immune response. Previously, we identified that a membrane-associated DHH-DHHA1 family protein from Sulfolobus islandicus efficiently degrades cOA.

High-resolution analysis of chromosome conformation in hyperthermophilic archaea
STAR Protocols, 2021 Summary: Chromosome conformation capture (3C) techniques are emerging as promising approaches to study genome organization in Archaea, the least understood domain of life in terms of chromosome biology. Here, we describe a 3C technique combined with deep

Identification of a system required for the functional surface localization of sugar binding proteins with class III signal peptides in Sulfolobus solfataricus [PDF]
, 2007 The hyperthermophilic archaeon Sulfolobus solfataricus contains an unusual large number of sugar binding proteins that are synthesized as precursors with a class III signal peptide.

Biosynthesis of caldariellaquinone in Sulfolobus spp [PDF]
Journal of Bacteriology, 1989 The biosynthesis of caldariellaquionone (CQ) was studied in species of Sulfolobus by measuring the incorporation of stable isotopically labeled tyrosines into CQ. By feeding a series of tyrosines labeled with deuterium or 13C and then measuring the extent and position at which label was incorporated into CQ by mass spectrometry, it was shown that more ...

mBio, 2020 The UV-inducible pili system of Sulfolobales (Ups) mediates the formation of species-specific cellular aggregates. Within these aggregates, cells exchange DNA to repair DNA double-strand breaks via homologous recombination. Substitution of the Sulfolobus

Biochemical characterization of a structure-specific resolving enzyme from Sulfolobus islandicus rod-shaped virus 2. [PDF]
PLoS ONE, 2011 Sulfolobus islandicus rod shaped virus 2 (SIRV2) infects the archaeon Sulfolobus islandicus at extreme temperature (70°C-80°C) and acidity (pH 3). SIRV2 encodes a Holliday junction resolving enzyme (SIRV2 Hjr) that has been proposed as a key enzyme in ...

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases. [PDF]
ProteinsABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

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.

Frontiers in Microbiology, 2012 An emerging model for investigating virus-host interactions in hyperthermophilic Archaea is the Fusellovirus-Sulfolobus system. The host, Sulfolobus, is a hyperthermophilic acidophile endemic to sulfuric volcanic-driven hot springs worldwide.
