Halobacteria: the evidence for longevity
Extremophiles, 1998Subterranean salt deposits are the remains of ancient hypersaline waters that presumably supported dense populations of halophilic microorganisms including representatives of the haloarchaea (halobacteria). Ancient subterranean salt deposits (evaporites) are common throughout the world, and the majority sampled to date appear to support diverse ...

Ribosomal proteins in halobacteria
Canadian Journal of Microbiology, 1989The amino acid sequences of 16 ribosomal proteins from archaebacterium Halobacterium marismortui have been determined by a direct protein chemical method. In addition, amino acid sequences of three proteins, S11, S18, and L25, have been established by DNA sequencing of their genes as well as by protein sequencing.

Genome mapping in halobacteria
Canadian Journal of Microbiology, 1989The goal of our research is to produce an ordered set of cosmid clones for each of several species of halobacteria for use in physical and genetic mapping. These maps will answer questions about genome evolution and about gene organization and regulation in this archaebacterial lineage.

Ubiquitin-like proteins in halobacteria
Journal of Basic Microbiology, 2002Within our studies of protein degradation, the presence of ubiquitinylated proteins in haloalkaliphilic archaea was investigated. We found that Natronococcus occultus proteins that react with antibodies raised against ubiquitin appear in different growth phases, particularly in the initial and exponential ones.

Expression of β2-adrenoceptors in halobacteria
Naunyn-Schmiedeberg's Archives of Pharmacology, 1997Halobacteria are halophilic representatives of the recently defined domain, the Archaea. Halobacterium salinarium belongs to this group of microorganisms and contains large amounts of bacteriorhodopsin in its membrane. Bacteriorhodopsin is a seven-transmembrane protein that consists of bacterio-opsin (BO), and the chromophore retinal, which is ...

Novel Isoprenoid Modified Proteins in Halobacteria
Biochemical and Biophysical Research Communications, 1994Incorporation of [3H]mevalonic acid-derived materials into proteins was studied with extremely halophilic archaebacteria, Halobacterium halobium and Halobacterium cutirubrum. Several labeled proteins were detected on SDS-polyacrylamide gel electrophoresis followed by fluorography.

Occurrence of megaplasmids in halobacteria
Journal of Applied Bacteriology, 1986Sixty‐five halobacteria, including culture collection and freshly isolated strains from widely differing geographical areas, were examined for the presence of high molecular weight plasmids by agarose gel electrophoresis. Seventy‐five per cent of all the strains were shown to harbour at least one plasmid. In the majority of strains

Inhibitors of eubacterial and eucaryotic DNA topoisomerases II induce topological changes and/or DNA cleavage in the plasmids of halobacteria. As in eubacteria, novobiocin halts DNA replication and induces positive supercoiling of plasmids in halobacteria.

Seven strains of extremely halophilic bacteria (Halobacterium spp., Halococcus spp., and Haloarcula sp.) fixed CO2 under light and dark conditions. Light enhanced CO2 fixation in Halobacterium halobium but inhibited it in Halobacterium volcanii and Haloarcula strain GN-1.
