High production of bacteriorhodopsin from wild type Halobacterium salinarum

Extremophiles, 2015
Bacteriorhodopsin (bR) is a trans-membrane proton pump found in the purple membrane of Halobacterium salinarum. This protein has high photochemical and photoelectric conversion efficiency and thermal stability, allowing it to withstand high temperatures, high salinity, and nutritionally-limited environments. The ability of this protein to convert light

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.

Effects of divalent cations on Halobacterium salinarum cell aggregation

Journal of Bioscience and Bioengineering, 2007
Ca(2+) was found to be essential for initiating Halobacterium salinarum CCM 2090 cell aggregation. The floc formed from such aggregation could easily be dissociated without cellular lysis by sodium citrate. Cr(2+), Mn(2+), Fe(3+), Co(2+), Ni(2+), Cu(2+), and Zn(2+) could replace Ca(2+). However, Mg(2+), Sr(2+), Mo(2+), Cd(2+), Sn(2+), Hg(2+), and Pb(2+)

Das rote Haloarchaeon Halobacterium salinarum

Biologie in unserer Zeit, 2017
ZusammenfassungDie Mikrobe des Jahres 2017 lebt zwar in harscher salzreicher Umgebung, hat aber einige Eigenschaften, die in der Biotechnologie oder in der medizinischen Forschung Anwendung finden. Neben dem Carotinoid Bakterioruberin und salzadaptierten Proteinen und Enzymen sind dies die lichtgetriebene Protonenpumpe Bakteriorhodopsin und Gasvesikel.

[Multicomponent nature of Halobacterium salinarum flagella].

Mikrobiologiia, 2008
Filaments of the flagellum of the halophilic archaeon Halobacterium salinarum consist of five flagellins: A1, A2, B1, B2, and B3, which are encoded by five genes localized in tandem in twoflgA and flgB operons. While the role of flagellins A1 and A2 has been determined, the role of the proteins, B operon products, is still unclear. A mutant strain of H.

Ca2+-dependent cell aggregation of halophilic archaeon, Halobacterium salinarum

Journal of Bioscience and Bioengineering, 2005
Halobacterium salinarum CCM 2090 exhibits a Ca(2+)-dependent cellular aggregation system. This process is caused by the interaction between Ca(2+) and aggregation factor(s). Although the aggregates formed are encased in matrix-like substances, such as bacterial biofilms, they are not attached to the abiotic substratum.

Structural Stabilization of [2Fe-2S] Ferredoxin from Halobacterium salinarum

Biochemistry, 2001
The ferredoxin of the extreme haloarchaeon Halobacterium salinarum requires high (>2 M) concentration of salt for its stability. We have used a variety of spectroscopic probes for identifying the structural elements which necessitate the presence of high salt for its stability.

A microprobe analysis of inorganic elements in Halobacterium salinarum

Cell Biology International, 2005
AbstractHalobacterium salinarum were grown on peptone agar containing 4.28 M NaCl, 0.036 M K and other salts. Stationary phase organisms were lifted onto carbon planchets, freeze‐dried, carbon coated and examined in a scanning electron microscope equipped with an X‐ray spectrometer.
