Emerg Top Life Sci (2022) 6 (6): 571–582.
Published: 15 November 2022
...Ahanjit Bhattacharya Archaea constitute one of the three fundamental domains of life. Archaea possess unique lipids in their cell membranes which distinguish them from bacteria and eukaryotes. This difference in lipid composition is referred to as ‘Lipid Divide' and its origins remain elusive...

... the initial identification of the archaea as a unique form of life. Emerging topics from this vibrant and rapidly expanding field of research are considered and detailed further in the articles within this issue. Correspondence: Nicholas P.

...Nicholas P. Robinson; Yan Liao; Solenne Ithurbide; Roshali T. de Silva; Susanne Erdmann; Iain G. Duggin The tubulin superfamily of cytoskeletal proteins is widespread in all three domains of life — Archaea , Bacteria and Eukarya . Tubulins build the microtubules of the eukaryotic cytoskeleton...

...Nicholas P. Robinson; Amy K. Schmid Gene regulation is intimately connected with metabolism, enabling the appropriate timing and tuning of biochemical pathways to substrate availability. In microorganisms, such as archaea and bacteria, transcription factors (TFs) often directly sense external cues...

...Nicholas P. Robinson; Nicole R. Buan Methanogens are anaerobic archaea that grow by producing methane gas. These microbes and their exotic metabolism have inspired decades of microbial physiology research that continues to push the boundary of what we know about how microbes conserve energy to grow...

...Nicholas P. Robinson; Alexander Mahnert; Marcus Blohs; Manuela-Raluca Pausan; Christine Moissl-Eichinger Forty years ago, archaea were described as a separate domain of life, distinct from bacteria and eukarya. Although it is known for quite a long time that methanogenic archaea are substantial...

...Nicholas P. Robinson; Liesbeth Lemmens; Rani Baes; Eveline Peeters An adequate response to a sudden temperature rise is crucial for cellular fitness and survival. While heat shock response (HSR) is well described in bacteria and eukaryotes, much less information is available for archaea, of which...

...Nicholas P. Robinson; Jean-François Brugère; John F. Atkins; Paul W. O'Toole; Guillaume Borrel The 22nd amino acid discovered to be directly encoded, pyrrolysine, is specified by UAG. Until recently, pyrrolysine was only known to be present in archaea from a methanogenic lineage ( Methanosarcinales...

... of the replisome during genome replication and DNA repair lags behind well-established bacterial and eukaryotic model systems. The archaea are evolutionarily very broad, but many studies in the major model systems of both Crenarchaeota and Euryarchaeota are starting to yield significant increases in understanding...

... with prokaryotes, the latter represented mainly by Bacteria. But any general theory of genome evolution must also account for the Archaea, a diverse and ecologically important group of prokaryotes that represent one of the primary domains of cellular life. Here, we survey the extant diversity of Bacteria...

... repair, while in eukaryotes, the RecJ-like protein Cdc45 (which has lost its nuclease activity) is a key component of the CMG (Cdc45–MCM–GINS) complex, the replicative DNA helicase that unwinds double-stranded DNA at the replication fork. In archaea, database searching identifies genes encoding one...
