Diversity and subcellular distribution of archaeal secreted proteins [PDF]
Frontiers in Microbiology, 2012 Secreted proteins make up a significant percentage of a prokaryotic proteome and play critical roles in important cellular processes such as polymer degradation, nutrient uptake, signal transduction, cell wall biosynthesis and motility.

Affinity Purification of an Archaeal DNA Replication Protein Network [PDF]
mBio, 2010 Nineteen Thermococcus kodakarensis strains have been constructed, each of which synthesizes a different His6-tagged protein known or predicted to be a component of the archaeal DNA replication machinery.

A Survey of Protein Structures from Archaeal Viruses [PDF]
Life, 2013 Viruses that infect the third domain of life, Archaea, are a newly emerging field of interest. To date, all characterized archaeal viruses infect archaea that thrive in extreme conditions, such as halophilic, hyperthermophilic, and methanogenic ...

Specificity and Function of Archaeal DNA Replication Initiator Proteins [PDF]
Cell Reports, 2013 Chromosomes with multiple DNA replication origins are a hallmark of Eukaryotes and some Archaea. All eukaryal nuclear replication origins are defined by the origin recognition complex (ORC) that recruits the replicative helicase MCM(2-7) via Cdc6 and ...

Biotechnological Uses of Archaeal Proteins. [PDF]
Archaea, 2015 Many industrial/biotechnological processes take place under extreme conditions of temperature, pH, salinity, or pressure which are not suitable for activities of proteins from model eukaryotic or common neutrophilic, mesophilic, and prokaryotic microorganisms. In contrast, Archaea offer a large panel of extremophile organisms that express proteins that

The Archaeal Lsm Protein Binds to Small RNAs [PDF]
Journal of Biological Chemistry, 2010 Proteins of the Lsm family, including eukaryotic Sm proteins and bacterial Hfq, are key players in RNA metabolism. Little is known about the archaeal homologues of these proteins. Therefore, we characterized the Lsm protein from the haloarchaeon Haloferax volcanii using in vitro and in vivo approaches. H.

Archaeal Unfoldase Counteracts Protein Misfolding Retinopathy in Mice [PDF]
The Journal of Neuroscience, 2018 Deregulation of cellular proteostasis due to the failure of the ubiquitin proteasome system to dispose of misfolded aggregation-prone proteins is a hallmark of various neurodegenerative diseases in humans. Microorganisms have evolved to survive massive protein misfolding and aggregation triggered by heat shock using their protein-unfolding ATPases ...

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.

Archaeal Phylogeny Based on Ribosomal Proteins [PDF]
Molecular Biology and Evolution, 2002 Until recently, phylogenetic analyses of Archaea have mainly been based on ribosomal RNA (rRNA) sequence comparisons, leading to the distinction of the two major archaeal phyla: the Euryarchaeota and the Crenarchaeota. Here, thanks to the recent sequencing of several archaeal genomes, we have constructed a phylogeny based on the fusion of the sequences

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.
