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.

Archaeal S-layer glycoproteins: post-translational modification in the face of extremes [PDF]
, 2014 Corresponding to the sole or basic component of the surface (S)-layer surrounding the archaeal cell in most known cases, S-layer glycoproteins are in direct contact with the harsh environments that characterize niches where Archaea can thrive ...

Translational coupling via termination-reinitiation in archaea and bacteria
Nature Communications, 2019 Archaea and bacteria often have gene pairs with overlapping stop and start codons, suggesting translational coupling. Here, Huber et al. analyse overlapping gene pairs from 720 genomes, and validate translational coupling via termination-reinitiation for

Cytochrome aa 3 in Haloferax volcanii [PDF]
Journal of Bacteriology, 2002 ABSTRACT A cytochrome in an extremely halophilic archaeon, Haloferax volcanii , was purified to homogeneity. This protein displayed a redox difference spectrum that is characteristic of a -type cytochromes and a CN − complex spectrum that indicates the ...

A genetic investigation of the KEOPS complex in halophilic Archaea. [PDF]
PLoS ONE, 2012 KEOPS is an important cellular complex conserved in Eukarya, with some subunits conserved in Archaea and Bacteria. This complex was recently found to play an essential role in formation of the tRNA modification threonylcarbamoyladenosine (t(6)A), and was

Growth Phase Dependent Cell Shape of Haloarcula
Microorganisms, 2021 Several haloarchaea are reported to be pleomorphic, while others exhibit remarkable shapes, such as squares. Recently, Haloferax volcanii was found to alter its morphology during growth.

Geochemical constraints on the Hadean environment from mineral fingerprints of prokaryotes [PDF]
, 2017 The environmental conditions on the Earth before 4 billion years ago are highly uncertain, largely because of the lack of a substantial rock record from this period.

A haloarchaeal ferredoxin electron donor that plays an essential role in nitrate assimilation [PDF]
, 2011 In the absence of ammonium, many organisms, including the halophilic archaeon Haloferax volcanii DS2 (DM3757), may assimilate inorganic nitrogen from nitrate or nitrite, using a ferredoxin-dependent assimilatory NO3-/NO2- reductase pathway.
