The Lrs14 family of DNA‐binding proteins as nucleoid‐associated proteins in the Crenarchaeal order Sulfolobales

Molecular Microbiology, Volume 123, Issue 2, Page 132-142, February 2025.
Crenarchaeal Sulfolobales organize their genome with small, abundant nucleoid‐associated proteins. Here, we shed light on the distinct function of the Lrs14 family of aspecific DNA‐binding proteins, position these members toward the “chromatin organizing” side of the spectrum of DNA binders and propose a regulatory role for Lrs14s in global gene ...

Characterization of the Cdc6 Homologues from the Euryarchaeon Thermoplasma acidophilum [PDF]

The Open Biochemistry Journal, 2008
Archaeal cell division cycle protein 6 (Cdc6) homologues are thought to be involved in the initiation process of DNA replication. In the present study, a biochemical characterization of the two Cdc6 proteins from the archaeon Thermoplasma acidophilum has been performed.

Phylogenomic analysis of proteins that are distinctive of Archaea and its main subgroups and the origin of methanogenesis

BMC Genomics, 2007
Background The Archaea are highly diverse in terms of their physiology, metabolism and ecology. Presently, very few molecular characteristics are known that are uniquely shared by either all archaea or the different main groups within archaea.

Parallelizing the cryo‐EM structure determination in THUNDER using GPU cluster

Engineering Reports, Volume 7, Issue 1, January 2025.
We designed a new computing approach specialized based on the 3D reconstruction algorithm of THUNDER for GPU to optimize and maximize the computing power of a single GPU, multiple GPU, and the GPU cluster, highlighted by a well‐designed cache structure and mixed computing precision of single‐precision and double‐precision.

Purification and properties of pyruvate kinase fromThermoplasma acidophilum [PDF]

FEMS Microbiology Letters, 1992
Thermoplasma acidophilum is a thermoacidophilic archaebacterium occupying a paradoxical place in phylogenetic trees (phenotypically it is a thermoacidophile but phylogenetically it classifies with the methanogens). To better understand its phylogeny, the pyruvate kinase from this organism is being investigated as a molecular marker. The enzyme has been

Extremophilic Microorganisms as a Source of Emerging Enzymes for the Food Industry: A Review

Food Science &Nutrition, Volume 13, Issue 1, January 2025.
Enzymes such as amylases, lipases, proteases, xylanases, laccases, pullulanase, chitinases, pectinases, esterases, isomerases, and dehydrogenases could be derived from extremophilic organisms like thermophiles, psychrophiles, acidophiles, alkaliphiles, and halophiles. These enzymes or extremozymes are applicable in the production of safe foods (such as

Structural Insights into the Rrp4 Subunit from the Crystal Structure of the Thermoplasma acidophilum Exosome

Biomolecules
The exosome multiprotein complex plays a critical role in RNA processing and degradation. This system governs the regulation of mRNA quality, degradation in the cytoplasm, the processing of short noncoding RNA, and the breakdown of RNA fragments.

Domain swapping: a mathematical model for quantitative assessment of structural effects

FEBS Open Bio, Volume 14, Issue 12, Page 2006-2025, December 2024.
The structure of a single chain interpreted on the basis of the hydrophobicity distribution (red line on profiles) represents the status with respect to an ideal hydrophobic core (blue) which is represented by a modified idealised hydrophobicity distribution (green line, upper part).

Exploiting Archaeal/Thermostable Enzymes in Synthetic Chemistry: Back to the Future?

ChemCatChem, Volume 16, Issue 21, November 11, 2024.
Thermostable and (hyper)thermophilic enzymes offer important opportunities for innovative, stereoselective and sustainable chemistry transformations. Many of these are archaeal enzymes that have evolved to operate under extreme conditions, including at elevated temperature.
