Stability of mRNA in the hyperthermophilic archaeon Sulfolobus solfataricus
RNA, 2002 Archaea-like bacteria are prokaryotes but, in contrast, use eukaryotic-like systems for key aspects of DNA, RNA, and protein metabolism. mRNA is typically unstable in bacteria and stable in eukaryotes, but little information is available about mRNA half-lives in archaea.

Transcriptional response to DNA damage in the archaeon Sulfolobus solfataricus [PDF]
Nucleic Acids Research, 2003 Exposure of cells to DNA-damaging agents triggers a complex biological response involving cell cycle arrest and modulation of gene expression. Genomic sequencing has revealed the presence of archaeal genes homologous to components of the eucaryal nucleotide excision repair (NER) pathway, which is involved in the repair of ultraviolet (UV) light-induced

Nucleases: From Primitive Immune Defenders to Modern Biotechnology Tools
Immunology, Volume 174, Issue 3, Page 279-286, March 2025.The evolution of nucleases is a remarkable journey, starting as primitive bacterial defenders against bacteriophages. Over time, nucleases have adapted to specialised roles within the immune systems of all forms of life, culminating in humans, where DNases and RNases serve as key components of the immune system.

Improving low-temperature activity of Sulfolobus acidocaldarius 2-keto-3-deoxygluconate aldolase
, 2009 Sulfolobus acidocaldarius 2-keto-3-deoxygluconate aldolase (SacKdgA) displays optimal activity at 95 degrees C and is studied as a model enzyme for aldol condensation reactions.

Identification, characterization and classification of prokaryotic nucleoid‐associated proteins
Molecular Microbiology, Volume 123, Issue 3, Page 206-217, March 2025.Nucleoid‐associated proteins (NAPs) structure DNA by either bending, wrapping, bridging, or forming protein filaments on the DNA. We review newly identified NAPs and provide a list of simple biochemical assays to study the DNA‐structuring properties of novel NAPs. Abstract Common throughout life is the need to compact and organize the genome.

Post-genomic characterization of metabolic pathways in Sulfolobus solfataricus
, 2012 The physiological functions and mode of actions of different biomolecules are of continuous interest and a prerequisite to fully understand and appreciate the potential of Archaea and their molecules.

Chromatin and gene regulation in archaea
Molecular Microbiology, Volume 123, Issue 3, Page 218-231, March 2025.Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

Regulation of DNA Topology in Archaea: State of the Art and Perspectives
Molecular Microbiology, Volume 123, Issue 3, Page 245-264, March 2025.DNA topoisomerases are ubiquitous enzymes that play a crucial role in regulating DNA supercoiling which affects fundamental biological processes involving DNA. In this review, we summarize the current understanding of regulation of supercoiling by DNA topoisomerases in the third domain of life, the Archaea, with a particular focus on three key model ...

Identification of novel components of the Ced and Ups systems in Saccharolobus islandicus REY15A
mLife, Volume 4, Issue 1, Page 17-28, February 2025.Abstract In Sulfolobales cells, transcription of the Ups (UV‐inducible pili of Sulfolobus) and Ced (Crenarchaeal system for exchange of DNA) genes is highly induced by DNA damage, and the two systems play key roles in pili‐mediated cell aggregation and chromosomal DNA import, respectively.
