Three-dimensional view of ultrafast dynamics in photoexcited bacteriorhodopsin [PDF]
Nature Communications, 2019 Bacteriorhodopsin (bR) is a light-driven proton pump. The primary photochemical event upon light absorption is isomerization of the retinal chromophore.

Bacteriorhodopsin folds through a poorly organized transition state. [PDF]
Journal of the American Chemical Society, 2014 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.

Collective exchange processes reveal an active site proton cage in bacteriorhodopsin [PDF]
, 2020 Proton translocation across membranes is vital to all kingdoms of life. Mechanistically, it relies on characteristic proton flows and modifications of hydrogen bonding patterns, termed protonation dynamics, which can be directly observed by fast magic ...

Abstract P-8: Properties of Light-Driven Proton Pump from Exiguobacterium sibiricum with Amphipathic Polymers [PDF]
International Journal of Biomedicine, 2019 Background: Rhodopsins are chromoproteins, which contain retinal, with various necessary functions for energy or photoreception of a cell. Many homologues of rhodopsins were found in the microorganisms of different taxa.

Peptide-Coated Bacteriorhodopsin-Based Photoelectric Biosensor for Detecting Rheumatoid Arthritis
Biosensors, 2023 An effective early diagnosis is important for rheumatoid arthritis (RA) management. This study reveals a novel RA detection method using bacteriorhodopsin as a photoelectric transducer, a light-driven proton pump in purple membranes (PMs). It was devised

Fusion of purple membranes triggered by immobilization on carbon nanomembranes
Beilstein Journal of Nanotechnology, 2021 A freestanding ultrathin hybrid membrane was synthesized comprising two functional layers, that is, first, a carbon nanomembrane (CNM) produced by electron irradiation-induced cross-linking of a self-assembled monolayer (SAM) of 4′-nitro-1,1′-biphenyl-4 ...
