Localization of subunits in proteasomes fromThermoplasma acidophilumby immunoelectron microscopy

, 1991
The subunit topography of the Thermoplasma acidophilum proteasome was determined by immunoelectron microscopy using monospecific antibodies directed against the two constituent subunits (alpha,beta).

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.

Chromatin and gene regulation in archaea

Molecular Microbiology, Volume 123, Issue 3, Page 218-231, March 2025.
Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

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.

Genetic Transfer in Action: Uncovering DNA Flow in an Extremophilic Microbial Community

Environmental Microbiology, Volume 27, Issue 2, February 2025.
Different taxa from all domains of life sharing the same environment are connected by DNA transfers that have occurred between them. Whereas most studies appraising horizontal genetic transfer (HGT) events employ methods that only identify protein‐coding genes, here we apply a gene‐agnostic method to metagenomic data for the first time.

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

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.

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 ...

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.
