Anti-CRISPR-Based and CRISPR-Based Genome Editing of Sulfolobus islandicus Rod-Shaped Virus 2

open access: yesViruses, 2018
Genetic engineering of viruses has generally been challenging. This is also true for archaeal rod-shaped viruses, which carry linear double-stranded DNA genomes with hairpin ends.

The transcriptional regulator EarA and intergenic terminator sequences modulate archaellation in Pyrococcus furiosus

open access: yesFrontiers in Microbiology, 2023
The regulation of archaellation, the formation of archaeal-specific cell appendages called archaella, is crucial for the motility, adhesion, and survival of archaeal organisms.

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]

open access: yes, 2019
Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.

Enzymatic Switching Between Archaeal DNA Polymerases Facilitates Abasic Site Bypass

open access: yesFrontiers in Microbiology, 2021
Abasic sites are among the most abundant DNA lesions encountered by cells. Their replication requires actions of specialized DNA polymerases. Herein, two archaeal specialized DNA polymerases were examined for their capability to perform translesion DNA ...

Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]

open access: yes, 2010
Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.

Putative Nucleotide-Based Second Messengers in the Archaeal Model Organisms Haloferax volcanii and Sulfolobus acidocaldarius

open access: yesFrontiers in Microbiology, 2021
Research on nucleotide-based second messengers began in 1956 with the discovery of cyclic adenosine monophosphate (3′,5′-cAMP) by Earl Wilbur Sutherland and his co-workers.

SICLE: A high-throughput tool for extracting evolutionary relationships from phylogenetic trees

open access: yes, 2016
We present the phylogeny analysis software SICLE (Sister Clade Extractor), an easy-to-use, high- throughput tool to describe the nearest neighbors to a node of interest in a phylogenetic tree as well as the support value for the relationship.

Short-term variability in the sedimentary BIT index of Lake Challa, East Africa over the past 2200 years : validating the precipitation proxy [PDF]

open access: yes, 2015
. The branched vs. isoprenoid index of tetraethers (BIT index) in Lake Challa sediments has been applied as a monsoon precipitation proxy on the assumption that the primary source of branched tetraether lipids (brGDGTs) was soil washed in from the lake's
