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.

The archaeo-eukaryotic GINS proteins and the archaeal primase catalytic subunit PriS share a common domain [PDF]

Biology Direct, 2010
Primase and GINS are essential factors for chromosomal DNA replication in eukaryotic and archaeal cells. Here we describe a previously undetected relationship between the C-terminal domain of the catalytic subunit (PriS) of archaeal primase and the B ...

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 ...

The archaeal PCNA proteins

Biochemical Society Transactions, 2011
PCNA (proliferating-cell nuclear antigen) is a ring-shaped protein that encircles duplex DNA and plays an essential role in many DNA metabolic processes. The PCNA protein interacts with a large number of cellular factors and modulates their enzymatic activities.

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

Journal of Bacteriology, 2007
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 ...

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.

Proteomic Characterization of Archaeal Ribosomes Reveals the Presence of Novel Archaeal-Specific Ribosomal Proteins

Journal of Molecular Biology, 2011
Protein synthesis occurs in macromolecular particles called ribosomes. All ribosomes are composed of RNA and proteins. While the protein composition of bacterial and eukaryotic ribosomes has been well-characterized, a systematic analysis of archaeal ribosomes has been lacking.

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

In silico identification of archaeal DNA-binding proteins

Bioinformatics
Abstract Motivation The rapid advancement of next-generation sequencing technologies has generated an immense volume of genetic data. However, these data are unevenly distributed, with well-studied organisms being disproportionately represented, while other organisms, such as from archaea ...

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.
