Lipidic cubic phase serial millisecond crystallography using synchrotron radiation

IUCrJ, 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

Sensors, 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 ...

Light-scattering changes in the bacteriorhodopsin photocycle [PDF]

, 1989
Light-scattering changes were found to accompany the bacteriorhodopsin photocycle in a suspension of purple membranes. A light-scattering signal comprises three phases, connected with (i) bR → M transition, (ii) transition of M to P intermediate (other ...

PHOTOACOUSTIC CALORIMETRY OF BACTERIORHODOPSIN PHOTOCYCLE

, 1983
Le cycle photochimique de la bactériorhodopsine a été étudié par photolyse par flash et par spectroscopie photoacoustique. Les spectres photoacoustigues de fréquence ont été simulés sur base d'un cycle branché, afin de déterminer les variations d ...

Opsins are phospholipid scramblases in all domains of life

mBio
Opsins are highly abundant retinal proteins in the membranes of photoheterotrophic bacteria. However, some microbial genomes encode an opsin but lack the gene for the final enzyme in retinal synthesis.

Role of internal water molecules in bacteriorhodopsin [PDF]

, 2000
Internal water molecules are considered to play a crucial role in the functional processes of proton pump proteins. They may participate in hydrogen-bonding networks inside proteins that constitute proton pathways.
