Archaeal membrane-associated proteases: insights on Haloferax volcanii and other haloarchaea [PDF]
Frontiers in Microbiology, 2015 The function of membrane proteases range from general house-keeping to regulation of cellular processes. Although the biological role of these enzymes in archaea is poorly understood, some of them are implicated in the biogenesis of the archaeal cell ...

Investigation of the global translational response to oxidative stress in the model archaeon Haloferax volcanii reveals untranslated small RNAs with ribosome occupancy [PDF]
mSphereOxidative stress induces a wide range of cellular damage, often causing disease and cell death. While many organisms are susceptible to the effects of oxidative stress, haloarchaea have adapted to be highly resistant.

Iron starvation results in up-regulation of a probable Haloferax volcanii siderophore transporter [PDF]
Frontiers in MicrobiologyThe response of the haloarchaeal model organism Haloferax volcanii to iron starvation was analyzed at the proteome level by data-independent acquisition mass spectrometry. Cells grown in minimal medium with normal iron levels were compared to those grown

A Novel Polyphosphate-Degrading Enzyme Confers Growth on Exogenous Polyphosphate in the Archaeon Haloferax volcanii. [PDF]
Environ MicrobiolA novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

Quantitative Mass Spectrometry by SILAC in Haloferax volcanii. [PDF]
Methods Mol Biol, 2022 The development of mass spectrometry (MS)-based proteomics methods has been critical in providing new insight about cellular processes and adaptations in all domains of life. While traditional MS-based methods are not inherently quantitative, technologies are now available to overcome this limitation.

Improved growth and morphological plasticity of Haloferax volcanii. [PDF]
Microbiology (Reading), 2021 Abstract Some microbes display pleomorphism, showing variable cell shapes in a single culture, whereas others differentiate to adapt to changed environmental conditions. The pleomorphic archaeon Haloferax volcanii commonly forms discoid-shaped (‘plate’) cells in culture, but may ...

A Small RNA Is Linking CRISPR–Cas and Zinc Transport
Frontiers in Molecular Biosciences, 2021 The function and mode of action of small regulatory RNAs is currently still understudied in archaea. In the halophilic archaeon Haloferax volcanii, a plethora of sRNAs have been identified; however, in-depth functional analysis is missing for most of ...

Genomic stability in the archaeae Haloferax volcanii and Haloferax mediterranei [PDF]
Journal of Bacteriology, 1995 Through hybridization of available probes, we have added nine genes to the macrorestriction map of the Haloferax mediterranei chromosome and five genes to the contig map of Haloferax volcanii. Additionally, we hybridized 17 of the mapped cosmid clones from H. volcanii to the H. mediterranei genome. The resulting 35-point chromosomal comparison revealed
