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 ...

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

[47] The classification of halobacteria
1982Publisher Summary This chapter describes the classification of halobacteria. Recently, the halobacteria seemed to form a very homogeneous bacterial group, but this may have been largely becaue of uniformly utilized enrichment and isolation procedures.

Considerable progress has been made in recent years in the understanding of the function of molecular components in eucaryotic and eubacterial signal transduction chains. Among the well known examples are processes dependent on G-proteins in eucaryotes and processes dependent on receptors, called methyl-accepting proteins, in eubacteria.

Development of Shuttle Vectors for Halobacteria
1989Abstract : We have developed systems for genetic analysis of halophilic archaebacteria. These include (1) transformation systems which we have shown to work efficiently in at least three genera of halobacteria, (2) shuttle vectors which can be selected in either halobacteria or E.

Signal Transduction in Halobacteria
1989The search for photosynthetically efficient green light and the avoidance of inefficient blue light or lethal ultra-violet light allows halobacteria to survive by means of photosynthesis in a natural habitat of brines and salt ponds under strong sunlight.

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.

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.

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.
