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.

On the two forms of bacteriorhodopsin [PDF]
FEBS Letters, 1994 In our previous work [(1993) FEBS Lett. 313, 248‐250; (1993) Biochem. Int. 30,461‐469] M‐intermediate formation of wild‐type bacteriorhodopsin was shown to involve two components differing in time constants (τ1 = 60–70 μs and τ2 = 220–250 μs), which were suggested to reflect two independent pathways of M‐intermediate formation.

Unravelling the folding of bacteriorhodopsin [PDF]
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2000 The folding mechanism of integral membrane proteins has eluded detailed study, largely as a result of the inherent difficulties in folding these proteins in vitro. The seven-transmembrane helical protein bacteriorhodopsin has, however, allowed major advances to be made, not just on the folding of this particular protein, but also on the factors ...

Spiking Neurons Derived from Proteinoid and Bacteriorhodopsin. [PDF]
ACS Appl Bio MaterWe investigate proteinoid-bacteriorhodopsin complexes as biomolecular spiking neurons for neuromorphic computing applications. Our system shows strong photoresponsive behavior through the integration of bacteriorhodopsin with self-assembled proteinoid ...

Electrostatics and electrodynamics of bacteriorhodopsin [PDF]
Biophysical Journal, 1996 The stationary electric dichroism of bacteriorhodopsin is in qualitative, but not quantitative, agreement with the orientation function for disks having a permanent dipole directed perpendicular to the plane and an induced dipole in the plane. Fits of the orientation function to data measured at low field strengths demonstrate: an increase of the ...

Meniscus-Mediated Imaging of Soft Biological Membranes Using 200 kN/m Ultra-Stiff 15 MHz MEMS AFM Probes. [PDF]
J Mol RecognitABSTRACT Coronaviruses, among other membrane‐enveloped viruses, can remain infectious on surfaces in ambient air for days. Many bacteria and fungi also expose their plasma membranes to air environments. Key survival strategies in air include hydrophobic coatings to prevent water loss and waxy or silica‐based resistant cell walls.

Photoisomerization detected in a fully wavelength-tunable rhodopsin mimic system. [PDF]
Acta Crystallogr D Struct BiolThe mechanism of retinal photoswitching is illuminated in a designed rhodopsin mimic. Two mechanisms, a conventional cis–trans isomerization and an unprecedented `photodehydration', are observed at atomic resolution in single crystals.We describe the photoisomerization of the retinylidene protonated Schiff base in human retinol‐binding protein II ...

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 ...
