Ecological and Genomic Attributes of Novel Bacterial Taxa That Thrive in Subsurface Soil Horizons. [PDF]
, 2019 While most bacterial and archaeal taxa living in surface soils remain undescribed, this problem is exacerbated in deeper soils, owing to the unique oligotrophic conditions found in the subsurface.

The archaeal ATPase PINA interacts with the helicase Hjm via its carboxyl terminal KH domain remodeling and processing replication fork and Holliday junction. [PDF]
, 2018 PINA is a novel ATPase and DNA helicase highly conserved in Archaea, the third domain of life. The PINA from Sulfolobus islandicus (SisPINA) forms a hexameric ring in crystal and solution.

Molecular machines in archaeal DNA replication
Current Opinion in Chemical Biology, 2011 The archaeal DNA replication apparatus is a simplified version of that of eukaryotes and has attracted attention as a tractable model system for the orthologous, but significantly more complex eukaryal machinery. A variety of archaeal model organisms have been investigated with strong emphasis on structural and biochemical analyses of replication ...

Histone stoichiometry and DNA circularization in archaeal nucleosomes [PDF]
Nucleic Acids Research, 1999 Recombinant (r)HMfB (archaealhistone B fromMethanothermusfervidus) formed complexes with increasing stability with DNA molecules increasing in length from 52 to 100 bp, but not with a 39 bp molecule. By using125I-labeled rHMfB-YY (an rHMfB variant with I31Y and M35Y replacements) and32P-labeled 100 bp DNA, these complexes, designated archaeal ...

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

Archaeal replicative primases can perform translesion DNA synthesis [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance DNA replicases stall at lesions during replication, potentially leading to genome instability. However, cells use specialized lesion bypass polymerases to restart stalled replisomes. Although most organisms possess these damage tolerance polymerases, capable of traversing blocking DNA lesions, many appear to lack these enzymes ...

Architectures of archaeal GINS complexes, essential DNA replication initiation factors
BMC Biology, 2011 Background In the early stage of eukaryotic DNA replication, the template DNA is unwound by the MCM helicase, which is activated by forming a complex with the Cdc45 and GINS proteins.

The FEBS Journal, 2018 How did the nucleosome, the fundamental building block of all eukaryotic chromatin, evolve? This central question has been impossible to address because the four core histones that make up the protein core of the nucleosome are so highly conserved in all eukaryotes.
