Dinucleoside Polyphosphates in Cellular Signaling: Function and Evolution Across Life
BioEssays, Volume 47, Issue 10, October 2025.Although discovered more than 50 years ago, the cellular functions of Ap4A and related dinucleotides remain largely enigmatic. To address this knowledge gap, we organized a conference showcasing recent research that highlights the critical role of Ap4A as a global regulator across all domains of life.

d-Xylose Degradation Pathway in the Halophilic Archaeon Haloferax volcanii [PDF]
Journal of Biological Chemistry, 2009 The pathway of D-xylose degradation in archaea is unknown. In a previous study we identified in Haloarcula marismortui the first enzyme of xylose degradation, an inducible xylose dehydrogenase (Johnsen, U., and Schönheit, P. (2004) J. Bacteriol. 186, 6198–6207).

ChemSusChem, Volume 18, Issue 16, August 6, 2025.The toxicity and biodegradability of deep eutectic solvents (DESs) can be evaluated using Haloferax mediterranei as a novel model organism. The haloarchaeon metabolizes specific DES components, highlighting its potential for DES bioremediation. These findings support the use of H.

Chromatin is an ancient innovation conserved between Archaea and Eukarya
eLife, 2012 The eukaryotic nucleosome is the fundamental unit of chromatin, comprising a protein octamer that wraps ∼147 bp of DNA and has essential roles in DNA compaction, replication and gene expression. Nucleosomes and chromatin have historically been considered

Identification of acetylated diether lipids in halophilic Archaea
MicrobiologyOpen, 2022 As a hallmark of Archaea, their cell membranes are comprised of ether lipids. However, Archaea‐type ether lipids have recently been identified in Bacteria as well, with a somewhat different composition: In Bacillales, sn‐glycerol 1‐phosphate is ...

Strategies for the Reconstitution and Purification of Haloarchael Protein RadA
Pakistan Journal of Analytical & Environmental Chemistry, 2019 DNA repair proteins in halophilic organisms are interesting to study in the context of understanding the dynamics of protein-DNA interaction and their adaptation to perform biochemical activities at high osmolarity. Successful expression and purification
