A comprehensive analysis of the importance of translation initiation factors for Haloferax volcanii applying deletion and conditional depletion mutants [PDF]
, 2013 Translation is an important step in gene expression. The initiation of translation is phylogenetically diverse, since currently five different initiation mechanisms are known.

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.

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

DNA Binding in High Salt: Analysing the Salt Dependence of Replication Protein A3 from the Halophile Haloferax volcanii [PDF]
, 2012 Halophilic archaea maintain intracellular salt concentrations close to saturation to survive in high-salt environments and their cellular processes have adapted to function under these conditions.

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.

Genetic and biochemical identification of a novel single-stranded DNA-binding complex in Haloferax volcanii [PDF]
, 2012 Single-stranded DNA (ssDNA)-binding proteins play an essential role in DNA replication and repair. They use oligonucleotide/oligosaccharide-binding (OB)-folds, a five-stranded β-sheet coiled into a closed barrel, to bind to ssDNA thereby protecting and ...

Inhibiting NAD+-dependent DNA ligase activity with 2-(cyclopentyloxy)-5'-deoxyadenosine (CPOdA) offers a new tool for DNA replication and repair studies in the model archaeon Haloferax volcanii [PDF]
, 2015 DNA ligases play an essential role in many aspects of DNA metabolism in all three domains of life. The haloarchaeal organism Haloferax volcanii encodes both ATP- and NAD+-dependent DNA ligase enzymes designated LigA and LigN, respectively.
