Crystal structure of Escherichia coli-expressed Haloarcula marismortui bacteriorhodopsin I in the trimeric form. [PDF]
PLoS ONE, 2014 Bacteriorhodopsins are a large family of seven-helical transmembrane proteins that function as light-driven proton pumps. Here, we present the crystal structure of a new member of the family, Haloarcula marismortui bacteriorhodopsin I (HmBRI) D94N mutant,

Annual Review of Physiology, 1999 ▪ Abstract Fourier transform infrared and Raman spectroscopy, solid-state NMR, and X-ray crystallography have contributed detailed information about the structural changes in the proton transport cycle of the light-driven pump, bacteriorhodopsin. The results over the past few years add up to a step-by-step description of the configurational changes ...

Artificial photosynthetic cell producing energy for protein synthesis
Nature Communications, 2019 Artificial cells need to be supplied with ATP as they lack internal systems of energy generation. Here the authors reconstruct ATP synthase and bacteriorhodopsins for light-driven ATP generation, powering transcription and translation.

Cation binding by bacteriorhodopsin [PDF]
Proceedings of the National Academy of Sciences, 1985 We have found that extensively washed purple membrane has about 1 calcium and 3-4 magnesium ions bound per bacteriorhodopsin molecule. When these divalent cations are removed by any of a variety of means, the pigment changes its color from purple to blue (λ max ≈ 600 nm).

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.
