AglQ is a novel component of the Haloferax volcanii N-glycosylation pathway. [PDF]

PLoS ONE, 2013
N-glycosylation is a post-translational modification performed by members of all three domains of life. Studies on the halophile Haloferax volcanii have offered insight into the archaeal version of this universal protein-processing event.

Haloglomus irregulare gen. nov., sp. nov., a New Halophilic Archaeon Isolated from a Marine Saltern [PDF]

, 2020
A halophilic archaeal strain, designated F16-60T, was isolated from Isla Cristina marine saltern in Huelva, Spain. Cells were pleomorphic, irregular, non-motile, and Gram-stain-negative. It produced red-pigmented colonies on agar plates.

Structure analysis of biologically important prokaryotic glycopolymers [PDF]

, 2013
Of the many post-translational modifications organisms can undertake, glycosylation is the most prevalent and the most diverse. The research in this thesis focuses on the structural characterisation of glycosylation in two classes of glycopolymer (

A bioluminescent reporter for the halophilic archaeon Haloferax volcanii. [PDF]

Extremophiles, 2020
Haloarchaea have evolved to thrive in hypersaline environments. Haloferax volcanii is of particular interest due to its genetic tractability; however, few in vivo reporters exist for halophiles. Haloarchaeal proteins evolved characteristics that promote proper folding and function at high salt concentrations, but many mesophilic reporter proteins lack ...

The Archaeal Proteome Project advances knowledge about archaeal cell biology through comprehensive proteomics

Nature Communications, 2020
While archaeal proteomics advanced rapidly, a comprehensive proteome database for archaea is lacking. Therefore, the authors here launch the Archaeal Proteome Project, a community-effort providing insights into archaeal cell biology via the combined ...

Nitrogen regulation of protein–protein interactions and transcript levels of GlnK PII regulator and AmtB ammonium transporter homologs in Archaea [PDF]

, 2013
Gene homologs of GlnK PII regulators and AmtB-type ammonium transporters are often paired on prokaryotic genomes, suggesting these proteins share an ancient functional relationship.

The crystal structure of Haloferax volcanii proliferating cell nuclear antigen reveals unique surface charge characteristics due to halophilic adaptation [PDF]

, 2009
Background: The high intracellular salt concentration re quired to maintain a halophilic lifestyle poses challenges to haloarchaeal proteins that must stay soluble, stable and functional in this extreme environment.

tRNA-like elements in Haloferax volcanii

Biochimie, 2012
All functional RNAs are generated from precursor molecules by a plethora of processing steps. The generation of mature RNA molecules by processing is an important layer of gene expression regulation catalysed by ribonucleases. Here, we analysed 5S rRNA processing in the halophilic Archaeon Haloferax volcanii. Earlier experiments showed that the 5S rRNA

Conserved substitution patterns around nucleosome footprints in eukaryotes and Archaea derive from frequent nucleosome repositioning through evolution. [PDF]

, 2013
Nucleosomes, the basic repeat units of eukaryotic chromatin, have been suggested to influence the evolution of eukaryotic genomes, both by altering the propensity of DNA to mutate and by selection acting to maintain or exclude nucleosomes in particular ...

Kleine Zinkfinger-Proteine in Haloferax volcanii [PDF]

, 2021
In der vorliegenden Arbeit wurde das Zinkfinger-µ-Protein HVO_2753 des halophilen Archaeons Haloferax volcanii hinsichtlich seiner biologischen Funktion und seiner Struktur charakterisiert. Zinkfinger-µ-Proteine wurden bisher nur sehr wenig untersucht, während ihnen jedoch in den letzten Jahren steigendes Interesse entgegengebracht wird. Im Genom von H.
