Delipidation of bacteriorhodopsin and reconstitution with exogenous phospholipid. [PDF]

open access: yes, 1980
Solubilizations of the purple membrane from Halobacterium halobium with the detergent Tritain X-100 followed by gel filtration in deoxycholate solution gave bacteriorhodopsin that was more than 99% free from endogenous lipid.

Photoanisotropic incoherent to coherent converter using a bacteriorhodopsin thin film [PDF]

open access: yes, 1995
We have fabricated a novel optically addressed spatial light modulator by using bacteriorhodopsin immobilized in a polymer thin film. This incoherent-to-coherent converter is based on photoinduced anisotropy, as distinguished from previously reported ...

Time-Resolved Resonance Raman Spectroscopy of Retinal Proteins with Continuous-Wave Excitation—A Fundamental Methodology Revisited

open access: yesPhotochem
Time-resolved (TR) resonance Raman (RR) spectroscopy with continuous-wave excitation is a fundamental technique that has contributed substantially to the understanding of the structure and dynamics of retinal proteins.

Mapping the effects of specific radiation damage and solvent radiolysis in buffers and crystals with online UV–Vis absorption spectroscopy

open access: yesActa Crystallographica Section D, Volume 82, Issue 5, Page 504-515, May 2026.
Radiation‐induced changes during X‐ray crystallographic data collection can compromise concurrent spectroscopic studies. Suitable protocols to detect and identify spectral artefacts from crystallization buffers and cryoprotectants are essential for the reliable analysis of chromophoric ligands in macromolecules.Online UV–Vis absorption spectroscopy is ...

Spatial Organization of Bacteriorhodopsin in Model Membranes [PDF]

open access: yes, 2002
Bacteriorhodopsin is a proton-transporting membrane protein in Halophilic archaea, and it is considered a prototype of membrane transporters and a model for G-protein-coupled receptors.

Light Color‐Controlled pH‐Adjustment of Aqueous Solutions Using Engineered Proteoliposomes

open access: yesAdvanced Science
Controlling the pH at the microliter scale can be useful for applications in research, medicine, and industry, and therefore represents a valuable application for synthetic biology and microfluidics.

The Conformational Switches of a Bacterial Light‐Driven Sodium Pump Characterized by Time‐Resolved Resonance Raman Spectroscopy

open access: yesChemPhysChem, Volume 27, Issue 7, 14 April 2026.
The microbial retinal protein KR2 (Krokinobacter eikastus) is a light‐driven outward Na+ pump, which is coupled to the photocycle of the chromophore. Using time‐resolved continuous‐wave pump‐probe resonance Raman spectroscopy, the operational switches for ion transport are identified, which are the transitions to a specific Schiff base sub‐state and ...

Bacteriorhodopsin Folds through a Poorly Organized Transition State [PDF]

open access: yes, 2015
The folding mechanisms of helical membrane proteins remain largely uncharted. Here we characterize the kinetics of bacteriorhodopsin folding and employ φ-value analysis to explore the folding transition state.

Lipidic cubic phase serial millisecond crystallography using synchrotron radiation

open access: yesIUCrJ, 2015
Lipidic cubic phases (LCPs) have emerged as successful matrixes for the crystallization of membrane proteins. Moreover, the viscous LCP also provides a highly effective delivery medium for serial femtosecond crystallography (SFX) at X-ray free-electron ...

Versatile Protein-A Coated Photoelectric Immunosensors with a Purple-Membrane Monolayer Transducer Fabricated by Affinity-Immobilization on a Graphene-Oxide Complexed Linker and by Shear Flow

open access: yesSensors, 2018
Bacteriorhodopsin-embedded purple membranes (PM) have been demonstrated to be a sensitive photoelectric transducer for microbial detection. To efficiently prepare versatile BR-based immunosensors with protein A as antibody captures, a large, high ...
