The bindosome is a structural component of the Sulfolobus solfataricus cell envelope [PDF]

Extremophiles, 2011
Sugar binding proteins of the thermoacidophile Sulfolobus solfataricus function together with ABC transporters in the uptake of sugars. They are synthesized as precursors with a class III signal peptide that are normally found in archaeal flagellins and bacterial type IV pilins. The functional expression of sugar binding proteins at the cell surface is

Control of cyclic oligoadenylate synthesis in a type III CRISPR system

eLife, 2018
The CRISPR system for prokaryotic adaptive immunity provides RNA-mediated protection from viruses and mobile genetic elements. When viral RNA transcripts are detected, type III systems adopt an activated state that licenses DNA interference and synthesis

Analysis of nucleotide insertion opposite urea and translesion synthesis across urea by DNA polymerases

Genes and Environment, 2022
Urea (Ua) is produced in DNA as the result of oxidative damage to thymine and guanine. It was previously reported that Klenow fragment (Kf) exo− incorporated dATP opposite Ua, and that DNA polymerase β was blocked by Ua.

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

ChemBioChem, 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

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.

A Spotlight on Archaea in Humans, Livestock and Poultry: A Review

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
The microbiota includes prokaryotes (archaea and bacteria) and eukaryotes. Archaea are single‐celled prokaryotes and essential part of gut microbiome. Researches on archaea in ruminants and humans are more than mono‐gastric. The low abundance of archaea in the gut depends on the method used (metagenomics or meta‐transcriptomic) and age of people or ...

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

Distinct Patterns of Antibiotic Sensitivities in Ammonia‐Oxidising Archaea

Environmental Microbiology, Volume 27, Issue 3, March 2025.
Antibiotic sensitivity varies between different strains of ammonia‐oxidising archaea. The results of this study will be useful for selective enrichment and development of a genetic system for ammonia‐oxidising archaea. ABSTRACT Ammonia‐oxidising archaea (AOA) are important microorganisms contributing towards the nitrogen flux in the environment. Unlike

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.
