Ubiquitin-like Small Archaeal Modifier Proteins (SAMPs) in Haloferax volcanii [PDF]

Nature, 2010
Archaea, one of three major evolutionary lineages of life, encode proteasomes highly related to those of eukaryotes. In contrast, archaeal ubiquitin-like proteins are less conserved and not known to function in protein conjugation.

Archaeal chromatin proteins

Science China Life Sciences, 2012
Archaea, along with Bacteria and Eukarya, are the three domains of life. In all living cells, chromatin proteins serve a crucial role in maintaining the integrity of the structure and function of the genome. An array of small, abundant and basic DNA-binding proteins, considered candidates for chromatin proteins, has been isolated from the Euryarchaeota

Evolutionary conservation of ubiquitin-like protein urmylation as revealed by URM1 gene shuffle from archaea to yeast [PDF]

Communications Biology
Urm1 from yeast is a unique ubiquitin-like protein with dual functionality. It has been shown to operate in tRNA thiolation and protein urmylation, combining features typical of bacterial sulfur carriers and classical ubiquitin-like modifiers.

Identification of Diverse Archaeal Proteins with Class III Signal Peptides Cleaved by Distinct Archaeal Prepilin Peptidases [PDF]

Journal of Bacteriology, 2006
ABSTRACT Most secreted archaeal proteins are targeted to the membrane via a tripartite signal composed of a charged N terminus and a hydrophobic domain, followed by a signal peptidase-processing site. Signal peptides of archaeal flagellins, similar to class III signal peptides of bacterial type IV pilins, are distinct in that ...

Archaeal protein biogenesis: posttranslational modification and degradation [PDF]

Archaea, 2010
The study of Archaea at the DNA and RNA levels has provided considerable insight into replication, transcription, and other information-associated events which are either unique to this remarkable group of organisms or which were later found to also occur in Bacteria and/or Eukarya.

CetZ tubulin-like proteins control archaeal cell shape [PDF]

Nature, 2014
Tubulin is a major component of the eukaryotic cytoskeleton, controlling cell shape, structure and dynamics, whereas its bacterial homologue FtsZ establishes the cytokinetic ring that constricts during cell division. How such different roles of tubulin and FtsZ evolved is unknown.

Protein Adaptations in Archaeal Extremophiles [PDF]

Archaea, 2013
Extremophiles, especially those in Archaea, have a myriad of adaptations that keep their cellular proteins stable and active under the extreme conditions in which they live. Rather than having one basic set of adaptations that works for all environments, Archaea have evolved separate protein features that are customized for each environment.

Minimal Yet Powerful: The Role of Archaeal Small Heat Shock Proteins in Maintaining Protein Homeostasis

Frontiers in Molecular Biosciences, 2022
Small heat shock proteins (sHsp) are a ubiquitous group of ATP-independent chaperones found in all three domains of life. Although sHsps in bacteria and eukaryotes have been studied extensively, little information was available on their archaeal homologs

Comprehensive Bioinformatics Analysis of the Biodiversity of Lsm Proteins in the Archaea Domain

Microorganisms, 2023
The Sm protein superfamily includes Sm, like-Sm (Lsm), and Hfq proteins. Sm and Lsm proteins are found in the Eukarya and Archaea domains, respectively, while Hfq proteins exist in the Bacteria domain.

Conserved and lineage-specific hypothetical proteins may have played a central role in the rise and diversification of major archaeal groups

BMC Biology, 2022
Background Archaea play fundamental roles in the environment, for example by methane production and consumption, ammonia oxidation, protein degradation, carbon compound turnover, and sulfur compound transformations.
