The photocycle movie of photoactive yellow protein from nanoseconds to seconds

, 2001
The structural changes associated with the photocycle of photoactive yellow protein (PYP) was investigated. Ultrafast time-resolved x-ray crystallography techniques were used for the structural analysis.

Tuning the Photocycle Kinetics of Bacteriorhodopsin in Lipid Nanodiscs

, 2015
Monodisperse lipid nanodiscs are particularly suitable for characterizing membrane protein in near-native environment. To study the lipid-composition dependence of photocycle kinetics of bacteriorhodopsin (bR), transient absorption spectroscopy was ...

Crystallographic analysis of protein conformational changes in the bacteriorhodopsin photocycle

, 2000
A variety of neutron, X-ray and electron diffraction experiments have established that the transmembrane regions of bacteriorhodopsin undergo significant light-induced changes in conformation during the course of the photocycle.

A Multi-Scale–Multi-Stable Model for the Rhodopsin Photocycle

, 2014
We report a multi-scale simulation study of the photocycle of the rhodopsins. The quasi-atomistic representation (“united atoms” UA) of retinal is combined with a minimalist coarse grained (CG, one-bead-per amino acid) representation of the protein, in a

Development of sensitive elements based on photochromic bacteriorhodopsin for fibre optic sensors [PDF]

, 2007
This work focuses on the development of sensitive elements incorporating bacteriorhodopsin thin films for fibre optic sensors. The sensing principle is based on monitoring optical properties of the bacteriorhodopsin thin films during changes of ...

Deuterium Isotope Effects in the Photocycle Transitions of the Photoactive Yellow Protein

, 2008
The Photoactive Yellow Protein (PYP) from Halorhodospira halophila (formerly Ectothiorhodospira halophila) is increasingly used as a model system. As such, a thorough understanding of the photocycle of PYP is essential.

Electrogenic photocycle of the 13-cis retinal-containing bacteriorhodopsin with an M intermediate involved

, 1988
It has been found that bacteriorhodopsin containing 13-cis-retinal as the chromophore (13-cis-bR) is competent in a one-photon photocycle which involves an M-type intermediate.

Spectrally silent transitions in the bacteriorhodopsin photocycle

, 1996
The photocycle kinetics of bacteriorhodopsin were analyzed from 0 to 40 degrees C at 101 wavelengths (330–730 nm). The data can be satisfactorily approximated by eight exponents.
