Biosynthesis of the Purple Membrane of Halobacteria [PDF]
Angewandte Chemie International Edition in English, 1976 AbstractHalobacteria are extremely specialized organisms. They live exclusively in saturated solutions of common salt. The cell membrane of these bacteria exhibit insular regions which can be isolated by membrane fractionation. These regions consist of a lipid matrix containing bateriorhodopsin molecules in a hexagonal crystalline arrangement ...

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.

On the gas vacuoles of the halobacteria
Archiv f�r Mikrobiologie, 1967The cells of Halobacterium sp., strain 5, contain a large number of highly refractile bodies of the type which Petter (1932) suggested were gas-filled vacuoles. The present studies support Petter's contention, but the evidence for the exact chemical nature of the vacuole content is still indirect.

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.

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.

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 ...

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.
