Sensory Transduction in Halobacterium

1985
Bacteria can sense and integrate outside stimuli and adapt to new environmental conditions, thereby revealing a simple mode of behavior. By a temporal sensing mechanism, bacteria orient indirectly in a biased three-dimensional random walk which finally leads the cells to accumulate in favorable surroundings or to avoid unfavorable areas.

Repair of UV damage in Halobacterium salinarum

Biochemical Society Transactions, 2003
Halobacterium is one of the few known Archaea that tolerates high levels of sunlight in its natural environment. Photoreactivation is probably its most important strategy for surviving UV irradiation and we have shown that both of the major UV photoproducts, cyclobutane pyrimidine dimers (CPDs) and (6–4) photoproducts, can be very efficiently repaired ...

Bacteriorhodopsin formation in Halobacterium halobium

Canadian Journal of Microbiology, 1976
Systematic examinations were made of factors influencing bacteriorhodopsin formation during the growth of Halobacterium halobium. Light-induced adenosine triphosphate (ATP) production and [14C]proline uptake were used as measures of functional ability of the purple membrane.

Polar lipid composition of a new halobacterium

Systematic and Applied Microbiology, 1987
Investigations of the polar lipid composition of a new aerobic, extremely halophilic aracheabacterium capable of nitrate reduction have shown that this organism contains two previously unknown phospholycolipids derived from diphytanyl glycerol diethers.

Factors Influencing the Retention of K in a Halobacterium

1975
The cells of at least two species of Halobacterium contain 3–4 mol of potassium and require for survival a similar concentration of NaC1 in the outside medium (Christian and Waltho, 1962; Ginzburg et al, 1970). It has been suggested (Ginzburg et al, 1970, 1971a, b) that the retention of cell potassium is not directly dependent upon metabolism.

Iron-uptake in the Euryarchaeon Halobacterium salinarum

BioMetals, 2007
Iron-uptake is well studied in a plethora of pro- and eukaryotic organisms with the exception of Archaea, which thrive mainly in extreme environments. In this study, the mechanism of iron transport in the extremely halophilic Euryarchaeon Halobacterium salinarum strain JW 5 was analyzed.

Proteomanalysen an Halobacterium salinarum

2005
Im Rahmen dieser Arbeit wurden verschiedene Proteome von H. salinarum untersucht, die nach zellulären Kompartimenten unterschieden wurden in (1) das Flagellarmotor-Proteom (2) das Cytosolproteom und (3) das Membranproteom. Die Untersuchung des Flagellarmotors erfolgte hauptsächlich auf struktureller Basis mittels Elektronenmikroskopie.

Isotopic Labeling of Proteins in Halobacterium salinarum

2015
It is often necessary to obtain isotopically labeled proteins containing (15)N, (13)C, or (2)H for nuclear magnetic resonance; and (2)H for small-angle neutron scattering or neutron diffraction studies. To achieve uniform isotopic labeling, protein expression is most commonly performed in Escherichia coli or yeast using labeled media. However, proteins
