DNA-Interacting Characteristics of the Archaeal Rudiviral Protein SIRV2_Gp1 [PDF]
Viruses, 2017 Whereas the infection cycles of many bacterial and eukaryotic viruses have been characterized in detail, those of archaeal viruses remain largely unexplored. Recently, studies on a few model archaeal viruses such as SIRV2 (Sulfolobus islandicus rod-shaped virus) have revealed an unusual lysis mechanism that involves the formation of pyramidal egress ...

Frontiers in Molecular Biosciences, 2021 The eukaryotic single-stranded DNA binding factor replication protein A (RPA) is essential for DNA replication, repair and recombination. RPA is a heterotrimer containing six related OB folds and a winged helix-turn-helix (wH) domain.

Evolutionary rates and gene dispensability associate with replication timing in the Archaeon Sulfolobus islandicus [PDF]
, 2010 In bacterial chromosomes, the position of a gene relative to the single origin of replication generally reflects its replication timing, how often it is expressed, and consequently, its rate of evolution.

Thermostable archaealO6-alkylguanine-DNA alkyltransferases [PDF]
Proceedings of the National Academy of Sciences, 1998 Archaea represent some of the most ancient organisms on earth, and they have relatively uncharacterized DNA repair processes. We now show, using anin vitroassay, that extracts of two Crenarchaeota (Sulfolobus acidocaldariusandPyrobaculum islandicum)and two Euryarchaeota (Pyrococcus furiosusandThermococcus litoralis) contain the DNA repair proteinO6 ...

Advanced Science, EarlyView.Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

Characterization of an archaeal two-component system that regulates methanogenesis in Methanosaeta harundinacea. [PDF]
PLoS ONE, 2014 Two-component signal transduction systems (TCSs) are a major mechanism used by bacteria in response to environmental changes. Although many sequenced archaeal genomes encode TCSs, they remain poorly understood. Previously, we reported that a methanogenic

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin
Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Frontiers in Microbiology, 2014 The elaborate eukaryotic DNA replication machinery evolved from the archaeal ancestors that themselves show considerable complexity. Here we discuss the comparative genomic and phylogenetic analysis of the core replication enzymes, the DNA polymerases ...

Early Evolution of Transcription Systems and Divergence of Archaea and Bacteria
Frontiers in Molecular Biosciences, 2021 DNA template-dependent multi-subunit RNA polymerases (RNAPs) found in all three domains of life and some viruses are of the two-double-Ψ-β-barrel (DPBB) type.
