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 ...

Bacteriorhodopsin: Would the real structural intermediates please stand up?
Biochimica et Biophysica Acta, 2015 BACKGROUND Bacteriorhodopsin (bR) is the simplest known light driven proton pump and has been heavily studied using structural methods: eighty four X-ray diffraction, six electron diffraction and three NMR structures of bR are deposited within 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.

Methods and Protocols, 2020 The light-driven proton pump bacteriorhodopsin (BR) from the extreme halophilic archaeon Halobacterium salinarum is a retinal-binding protein, which forms highly ordered and thermally stable 2D crystals in native membranes (termed purple membranes).

Light-Controlled Spin Filtering in Bacteriorhodopsin
Nano letters (Print), 2015 The role of the electron spin in chemistry and biology has received much attention recently owing to to the possible electromagnetic field effects on living organisms and the prospect of using molecules in the emerging field of spintronics.

The role of topology in electrical properties of bacteriorhodopsin and rat olfactory receptor I7
, 2010 We report on electrical properties of the two sensing proteins: bacteriorhodopsin and rat olfactory receptor OR-I7. As relevant transport parameters we consider the small-signal impedance spectrum and the static current-voltage characteristics ...

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Engineering a Robust Photovoltaic Device with Quantum Dots and Bacteriorhodopsin
The journal of physical chemistry. C, Nanomaterials and interfaces, 2014 We present a route toward a radical improvement in solar cell efficiency using resonant energy transfer and sensitization of semiconductor metal oxides with a light-harvesting quantum dot (QD)/bacteriorhodopsin (bR) layer designed by protein engineering.
