THE ROLE OF BACTERIORHODOPSIN IN LIGHT HARVESTING AND ATP PRODUCTION BY HALOBACTERIUM SALINARUM CELLS

SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings, 2022
Halobacterium salinarum is an extremely halophilic marine Gram-negative obligate aerobic archaeon. Despite its name, this is not a bacterium, but rather a member of the domain Archaea, which lives in hypersaline lakes.

The membrane proteome of Halobacterium salinarum

PROTEOMICS, 2005
AbstractThe identification of 114 integral membrane proteins from Halobacterium salinarum was achieved using liquid chromatography/tandem mass spectrometric (LC/MS/MS) techniques, representing 20% of the predicted alpha‐helical transmembrane proteins of the genome.

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.

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 ...

Investigations of iron uptake in Halobacterium salinarum

Biochemical Society Transactions, 2002
The iron transport in the extremely halophilic Euryarchaeon Halobacterium salinarum JW5 was investigated. Experiments to detect endogenous siderophores from H. salinarum failed, but it was able to utilize exogenous siderophores. Measurement of the uptake of 55Fe and [14C]citrate gave evidence only for the accumulation of iron.

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

The Low Molecular Weight Proteome of Halobacterium salinarum

Journal of Proteome Research, 2007
Systematic investigation of low molecular weight proteins (LMW, below 20 kDa) in the archaeon Halobacterium salinarum resulted in a 6-fold enhancement of the identification rate, reaching 35% of the theoretical proteome in that size range. This was achieved by optimization of common protocols for protein analysis with general applicability.

Reconstruction, modeling & analysis of Halobacterium salinarum R-1 metabolism

Mol. BioSyst., 2008
We present a genome-scale metabolic reconstruction for the extreme halophile Halobacterium salinarum. The reconstruction represents a summary of the knowledge regarding the organism's metabolism, and has already led to new research directions and improved the existing annotation.

Comparative Femtosecond Spectroscopy of Primary Photoreactions of Exiguobacterium sibiricum Rhodopsin and Halobacterium salinarum Bacteriorhodopsin.

Journal of Physical Chemistry B, 2021
The primary stages of the Exiguobacterium sibiricum rhodopsin (ESR) photocycle were investigated by femtosecond absorption laser spectroscopy in the spectral range of 400-900 nm with a time resolution of 25 fs.

Key determinants for signaling in the sensory rhodopsin II/transducer complex are different between Halobacterium salinarum and Natronomonas pharaonis

FEBS Letters, 2023
The cell membrane of Halobacterium salinarum contains a retinal‐binding photoreceptor, sensory rhodopsin II (HsSRII), coupled with its cognate transducer (HsHtrII), allowing repellent phototaxis behavior for shorter wavelength light.
