Occupancy of the HbYX hydrophobic pocket is sufficient to induce gate opening in the archaeal 20S proteasomes [PDF]
Enhancing proteasome function has been a long-standing but challenging target of interest for the potential treatment of neurodegenerative diseases, emphasizing the importance of understanding proteasome activation mechanisms.

Expanded Archaeal Genomes Shed New Light on the Evolution of Isoprenoid Biosynthesis [PDF]
Isoprenoids and their derivatives, essential for all cellular life on Earth, are particularly crucial in archaeal membrane lipids, suggesting that their biosynthesis pathways have ancient origins and play pivotal roles in the evolution of early life ...

Functional Characterization of Serotonin N-Acetyltransferase in Archaeon Thermoplasma volcanium [PDF]
Serotonin N-acetyltransferase is the penultimate enzyme in the melatonin biosynthetic pathway that catalyzes serotonin into N-acetylserotonin. Many SNAT genes have been cloned and characterized from organisms ranging from bacteria to plants and mammals ...

Escherichia coli RimI Encodes Serotonin N-Acetyltransferase Activity and Its Overexpression Leads to Enhanced Growth and Melatonin Biosynthesis [PDF]
Serotonin N-acetyltransferase (SNAT) functions as the penultimate or final enzyme in melatonin biosynthesis, depending on the substrate. The Escherichia coli orthologue of archaeal SNAT from Thermoplasma volcanium was identified as RimI (EcRimI), with 42%

Microbial diversity of hot springs of the Kuril Islands [PDF]
The Kuril Islands are located in the Far-East of Russia and enriched with shallow and terrestrial hot springs. Prokaryotic diversity of Kuril geothermal environments has been studied fragmentarily and mainly by culture-dependent methods. We performed the

Removal of diclofenac from aqueous solutions by adsorption on thermo-plasma expanded graphite
The adsorption of diclofenac on thermo-plasma expanded graphite (a commercial product) from water solutions was investigated. The adsorbent material was characterized by SEM, TEM, BET, Raman and X-ray diffraction analyses. Typical diffractogram and Raman
