Circular RNAs in Archaea
Published: August 31, 2025 10:00
Circular RNA molecules were first described more than 40 years ago. However, it is only recently that the broadness of their phylogenetic distribution has been revealed. Since their discoveries, numerous studies have characterized the molecular mechanisms…
Structural basis of substrate diversity and functional evolution of archaeal RNA-splicing endonucleases
Published: August 30, 2025 10:00
Maturation of transfer RNA molecules often requires removal of intronic sequences by endonucleases that recognize diverse RNA secondary structures. Archaeal splicing endonucleases [versatile RNA-splicing endonucleases (VSENs)] exhibit remarkable substrate…
Optimization of copper bioremoval from hypersaline environments by the halophilic archaeon Halalkalicoccus sp. Dap5 via response surface methodology
Published: August 27, 2025 10:00
Copper pollution in hypersaline environments poses a significant challenge due to the inefficiency of conventional bioremediation strategies under high salinity and metal stress. Halophilic archaea represent a promising solution for heavy metal removal in…
DPANN archaea
Published: August 19, 2025 10:00
Archaea are one of the two primary domains of life alongside Bacteria. Extant archaea play an important role in global nutrient cycles and comprise members that were crucial for the evolution of life on Earth including the origin of eukaryotic cells…
The Ammonia Oxidising Archaeon Nitrosopumilus maritimus Does Not Alter Iodine Oxidation State in Oxic Seawater
Published: August 10, 2025 10:00
We investigate the potential for the globally distributed marine ammonia oxidising archaeon (AOA) Nitrosopumilus maritimus to oxidise iodide (I^(-)), with the aim of identifying a key driver of seawater iodate (IO(3) ^(-)) renewal. Batch cultures of N.…
DPANN Archaea and CPR Bacteria: insights into early cellular evolution?
Published: August 7, 2025 10:00
Cultivation-independent techniques have facilitated the discovery of a diversity of thus far uncultivated organisms and led to the identification of new branches within the tree of life. This has reshaped the general view of key evolutionary processes and…
Biophysical characterization and solution structure of the cannulae-forming protein CanA from the hyperthermophilic archaeon Pyrodictium abyssi
Published: August 5, 2025 10:00
CanA from Pyrodictium abyssi, the main constituent of the extracellular protein network of this archaeon, forms a hollow-fiber network in the presence of divalent ions. The polymerization of CanA induced by divalent ions is characterized by (at least) two…
