The bacteriorhodopsin gene. [PDF]

Proceedings of the National Academy of Sciences, 1981
The bacteriorhodopsin gene has been identified in a 5.3-kilobase restriction endonuclease fragment isolated from Halobacterium halobium DNA, using a cloned cDNA fragment as the probe. Of the 1229 nucleotides whose sequence was determined in the genomic fragment, 786 correspond to the structural gene of bacteriorhodopsin, 360 are upstream from the ...

Chromophore motion during the bacteriorhodopsin photocycle: polarized absorption spectroscopy of bacteriorhodopsin and its M-state in bacteriorhodopsin crystals. [PDF]

The EMBO Journal, 1991
The three-dimensional crystallization of bacteriorhodopsin was systematically investigated and the needle-shaped crystal form analysed. In these crystals the M-intermediate forms 10 times faster and decays 15 times more slowly than in purple membranes. Polarized absorption spectra of the crystals were measured in the dark and light adapted states.

Carbon Contacts to Proteins Enable Robust, Biocompatible Electronic Junctions with Near‐Activation‐less Conduction Down to 10 K

Advanced Functional Materials, EarlyView.
A robust solid‐state protein junction with a semi‐transparent eC/Au electrode allows photoexcitation of the bacterio‐rhodopsin, bR layer, to isomerize the bR retinal. The resulting photo‐response shows the protein is functional in the solid‐state junction.

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Photo‐Modulated Proton Transport in Merocyanine Metastable‐State Photoacid Based Polymers

Small, EarlyView.
The covalent incorporation of merocyanine metastable‐state photoacid into soft polymers imparts conductivity to otherwise insulating matrices, allowing light‐triggered control of charge and structure, offering a new platform for photo‐responsive, ion‐conducting materials.

Verbesserte Auflösung in der ESR‐Spektroskopie unter Verwendung von para‐Wasserstoff‐Matrizen

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Wir demonstrieren die vorteilhaften Eigenschaften von festen para‐Wasserstoff (p‐H2)‐Matrizen für die Elektronenspinresonanz (ESR) Spektroskopie, indem wir das 2,2,6,6‐Tetramethylpiperidinyloxyl (TEMPO)‐Radikal und ein in situ erzeugtes P‐zentriertes Monoradikal untersuchen. Die spektrale Auflösung des P‐zentrierten Radikals in p‐H2 ist im Vergleich zu

Photochemical reaction of bacteriorhodopsin

FEBS Letters, 1976
Halobacterium halobium utilizes light both as a stimulus for phototaxis [l] and as an energy source for creating a proton gradient across the cell membrane which in turn produces ATP [2] . The photoreceptive pigment of this bacterium was first investigated by Oesterhelt and Stoeckenius [3] who showed that it is the only protein lying in so-called ...

Enhanced Resolution in EPR Spectroscopy Using para‐Hydrogen Matrices

Angewandte Chemie International Edition, Volume 65, Issue 6, 2 February 2026.
We demonstrate the advantageous properties of solid para‐hydrogen (p‐H2) matrices for electron paramagnetic resonance (EPR) spectroscopy by investigating the 2,2,6,6‐tetramethylpiperidinyloxyl (TEMPO) radical and an in situ generated P‐centered mono‐radical.
