Electronic and Structural Heterogeneity in the Diiron Center of Sulerythrin: Insights From Hybrid QM/MM Calculations. [PDF]
ChemphyschemQM/MM modeling of Sulerythrin (SulE) identifies three electronic states of its diiron center, differing in protonation and bridging ligands. The results reconcile crystallographic heterogeneity and reveal how subtle electronic and structural changes govern non‐heme diiron enzyme reactivity.

Evolutionary conservation of ubiquitin-like protein urmylation as revealed by URM1 gene shuffle from archaea to yeast [PDF]
Communications BiologyUrm1 from yeast is a unique ubiquitin-like protein with dual functionality. It has been shown to operate in tRNA thiolation and protein urmylation, combining features typical of bacterial sulfur carriers and classical ubiquitin-like modifiers.

The Effects of Temperature and Growth Phase on the Lipidomes of Sulfolobus islandicus and Sulfolobus tokodaii [PDF]
Life, 2015 The functionality of the plasma membrane is essential for all organisms. Adaption to high growth temperatures imposes challenges and Bacteria, Eukarya, and Archaea have developed several mechanisms to cope with these.

Versatile Genetic Tool Box for the Crenarchaeote Sulfolobus acidocaldarius
Frontiers in Microbiology, 2012 For reverse genetic approaches inactivation or selective modification of genes are required to elucidate their putative function. Sulfolobus acidocaldarius is a thermoacidophilic Crenarchaeon which grows optimally at 76 °C and pH 3.

Molecular analysis of 3D domain swapping in the acylphosphatase from Escherichia coli. [PDF]
Acta Crystallogr D Struct BiolStructures of the monomer and intertwined dimer of the acylphosphatase from E. coli shed light on the molecular basis of its 3D domain swapping.Three‐dimensional domain swapping is a mechanism by which proteins form oligomers. At present, the molecular basis that dictates whether some proteins fold in their monomeric form or as intertwined oligomers is

Archaeal GPN-loop GTPases involve a lock-switch-rock mechanism for GTP hydrolysis
mBio, 2023 Three GPN-loop GTPases, GPN1–GPN3, are central to the maturation and trafficking of eukaryotic RNA polymerase II. This GTPase family is widely represented in archaea but typically occurs as single paralogs.
