Nutrition of the Halophilic Archaebacterium, Haloferax volcanii
Systematic and Applied Microbiology, 1990Summary A synthetic medium containing glycerol and succinate as carbon sources, NH4Cl as nitrogen source, thiamine and biotin, as well as salts, supports growth of Haloferax volcanii and other halophilic archaebacteria. A number of single carbon compounds can also support growth, as can single nitrogen compounds (urea, histidine and glutamate).

The 2-oxoacid dehydrogenase multienzyme complex of Haloferax volcanii
Extremophiles, 2007Those aerobic archaea whose genomes have been sequenced possess four adjacent genes that, by sequence comparisons with bacteria and eukarya, appear to encode the component enzymes of a 2-oxoacid dehydrogenase multienzyme complex. However, no catalytic activity of any such complex has ever been detected in the archaea.

Novel glycoproteins of the halophilic archaeon Haloferax volcanii
Archives of Microbiology, 2000Archaea possess many eukaryote-like properties, including the ability to glycosylate proteins. Using oligosaccharide staining and lectin binding, this study revealed the existence of several glycosylated Haloferax volcanii membrane proteins, besides the previously reported surface layer (S-layer) glycoprotein.

Small RNAs of the halophilic archaeon Haloferax volcanii
Biochemical Society Transactions, 2009In recent years, sRNAs (small non-coding RNAs) have been found to be abundant in eukaryotes and bacteria and have been recognized as a novel class of gene expression regulators. In contrast, much less is known about sRNAs in archaea, except for snoRNAs (small nucleolar RNAs) that are involved in the modification of bases in stable RNAs.

Fructose transport byHaloferax volcanii
Canadian Journal of Microbiology, 1995Uptake of fructose by intact cells of Haloferax volcanii, one of the sugar-utilizing halobacteria, was examined with the following results. (i) The fructose transporter was inducible, (ii) Kinetic analysis showed a Ktof 0.37 μM and a Vmaxof 4.61 nmol∙mg protein−1∙min−1.

Amber suppression in the archaebacterium Haloferax volcanii
2009The purpose of this project was to test whether amber suppression can occur in Haloferax volcanii or not, and if so, to construct a H. volcanii strain that can suppress amber mutations. To achieve this goal, a putative amber suppressor was constructed from the tyrosine transfer RNA of H. volcanii.

Salty and Sweet: Protein Glycosylation in Haloferax volcanii
2011Ever since the discovery of the first glycosylated archaeal protein, namely the Halobacterium salinarum surface-layer glycoprotein some 35 years ago, research on haloarchaea has been at the forefront of efforts to decipher the archaeal version of N-glycosylation, a universal post-translational modification.

The Role of Homologous Recombination in Haloferax volcanii
2020The archaeon Haloferax volcanii is widely used to study DNA replication, recombination and repair. It is one of only two archaea which have been shown to replicate in the absence of replication origins. The main chromosome of H. volcanii lab strain has four replication origins, oriC1, oriC2, oriC3, and ori-pHV4.

Haloferax volcanii DS2 and Halobacterium salinarium GRB
1998Contig maps for two haloarchaeal genomes have been constructed to date: Haloferax volcanii DS2 (Charlebois et al., 1991) and Halobacterium salinarium GRB (St. Jean et al., 1994). Additionally, chromosomal macrorestriction maps are available from Haloferax mediterranei ATCC 33500 (Lopez-Garcia et al., 1992; Anton et al., 1994) and from Hb.
