Both, Haloferax mediterranei and Haloferax volcanii membranes contain ATPases which are capable of hydrolyzing ATP in presence of Mg2+ or Mn2+. The ATPases require high con centrations of NaCl, a pH value of 9, and high temperatures up to 60 °C. Free manganese ions inhibited the enzyme activity of either ATPase. The ATPases of Hf. mediterranei and Hf. vol canii, respectively, show different s...
Haloferax mediterranei, an extremely halophilic archaeon, has shown promise for production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) from unrelated cheap carbon sources. Here we report the complete genome (3,904,707 bp) of H. mediterranei CGMCC 1.2087, consisting of one chromosome and three megaplasmids.
A number of species of Haloferax genus (halophilic archaea) are able to grow microaerobically or even anaerobically using different alternative electron acceptors such as fumarate, nitrate, chlorate, dimethyl sulphoxide, sulphide and/or trimethylamine. This metabolic capability is also shown by other species of the Halobacteriaceae and Haloferacaceae families (Archaea domain) and it has been ma...
The structure of glucose dehydrogenase from the extreme halophile Haloferax mediterranei has been solved at 1.6-A resolution under crystallization conditions which closely mimic the "in vivo" intracellular environment. The decoration of the enzyme's surface with acidic residues is only partially neutralized by bound potassium counterions, which also appear to play a role in substrate binding. T...
The use of multiple origins for chromosome replication has been demonstrated in archaea. Similar to the dormant origins in eukaryotes, some potential origins in archaea appear to be inactive during genome replication. We have comprehensively explored the origin utilization in Haloferax mediterranei. Here we report three active chromosomal origins by genome-wide replication profiling, and demons...
The plasma membrane of Haloferax volcanii contains several glycoproteins, including a 98-kDa species. Using lectin-based chromatography, the glycoprotein was isolated and partially characterized. Sequence comparison, based on antibody binding as well as one-dimensional peptide maps show that the 98-kDa glycoprotein is distinct from the S-layer glycoprotein, the major glycoprotein in H. volcanii...
