Archaeal Life on Tangkuban Perahu- Sampling and Culture Growth in Indonesian Laboratories

open access: yesHayati Journal of Biosciences, 2012
The aim of the expedition to Tangkuban Perahu, West Java was to obtain archaeal samples from the solfatara fields located in Domas crater. This was one of the places, where scientists from the University of Regensburg Germany had formerly isolated ...

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1245-1258, June 2026.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

CRISPR-mediated gene silencing reveals involvement of the archaeal S-layer in cell division and virus infection

open access: yesNature Communications, 2019
The S-layer is a proteinaceous envelope often found in bacterial and archaeal cells. Here, the authors use CRISPR-based technology to silence slaB, encoding the S-layer membrane anchor, to show that an intact S-layer is important for cell division and ...

Asymmetric Reduction of Unactivated Alkenes

open access: yesChemistry – A European Journal, Volume 32, Issue 18, 14 May 2026.
Unactivated alkenes rank among the most inert functional groups in synthesis and their selective reduction remains challenging. This Review charts the evolution from classical metal‐catalyzed hydrogenation to radical hydrogen atom transfer (HAT) and emerging biocatalytic concepts, highlighting how complementary mechanistic strategies, including the ...

Genetic tools for Sulfolobus spp.: vectors and first applications [PDF]

open access: yes, 2018
Sulfolobus species belong to the best-studied archaeal organisms but have lacked powerful genetic methods. Recently, there has been considerable progress in the field of Sulfolobus genetics.

Acanthamoeba can propagate on thermophilic Sulfolobus spp.

open access: yes, 2013
Acanthamoeba isolation from extreme environments suggests that they may play a role in regulating archaeal densities and contribute to these ecosystems.

Two novel conjugative plasmids from a single strain of Sulfolobus [PDF]

open access: yes, 2006
Two conjugative plasmids (CPs) were isolated and characterized from the same 'Sulfolobus islandicus' strain, SOG2/4, The plasmids were separated from each other and transferred into Sulfolobus soltataricus.

The helicase activity of hyperthermophilic archaeal MCM is enhanced at high temperatures by lysine methylation

open access: yesFrontiers in Microbiology, 2015
Lysine methylation and methyltransferases are widespread in the third domain of life, archaea. Nevertheless, the effects of methylation on archaeal proteins wait to be defined.

Tn‐seq of Thermus thermophilus Genome Reveals Unexpected Tolerance to Insertions in Bacterial Common Essential Genes

open access: yesMicrobiologyOpen, Volume 15, Issue 2, April 2026.
Tn‐seq analysis of Thermus thermophilus genome reveals insertions in almost all genes, this is, there is no clear discrimination of essential genes. A similar result has not been reported in other Tn‐seq analysis of bacterial genomes so far. The polyploidy of the Thermus genome could explain the apparent non‐essentiality of key genes.
