Photocycle of Cyanobacteriochrome TePixJ [PDF]

Biochemistry, 2020
Due to the recent advances in X-ray free electron laser techniques the bilin-containing cyanobacteriochrome photoreceptors have become prime targets for the ever expanding field of time-resolved structural biology.

Chemical and functional studies on the importance of purple membrane lipids in bacteriorhodopsin photocycle behavior

FEBS Letters, 1996
In native purple membrane (PM), there are approximately 1 squalene, 2 glycolipid sulfate (GLS), and 6 phospholipid (PL) molecules per bacteriorhodopsin (BR) monomer [10].

A new intermediate in the photocycle of bacteriorhodopsin

FEBS Letters, 1986
With increasing pH (6.0 to 10.5) there is an increasing discrepancy between the recovery rate of bacteriorhodopsin after a flash and the decay rates of the key photointermediates, Mfast and Mslow, which is not predicted by any model of the photocycle ...

Factors That Control the Chemistry of the LOV Domain Photocycle [PDF]

, 2023
Algae, plants, bacteria and fungi contain Light-Oxygen-Voltage (LOV) domains that function as blue light sensors to control cellular responses to light. All LOV domains contain a bound flavin chromophore that is reduced upon photon absorption and forms a

Early picosecond events in the photo cycle of Bacteriorhodopsin [PDF]

, 1986
The primary processes of the photochemical cycle of light-adapted bacteriorhodopsin (BR) were studied by various experimental techniques with a time resolution of 5 × 10-13 s. The following results were obtained.

Incoherent manipulation of the photoactive yellow protein photocycle with dispersed pump-dump-probe spectroscopy [PDF]

, 2004
Photoactive yellow protein is the protein responsible for initiating the “blue-light vision” of Halorhodospira halophila. The dynamical processes responsible for triggering the photoactive yellow protein photocycle have been disentangled with the use of ...

Effect of lipid bilayer properties on the photocycle of green proteorhodopsin [PDF]

, 2015
The significance of specific lipids for proton pumping by the bacterial rhodopsin proteorhodopsin (pR) was studied. To this end, it was examined whether pR preferentially binds certain lipids and whether molecular properties of the lipid environment ...

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 ...

Characterization of the Proton-Transporting Photocycle of Pharaonis Halorhodopsin

, 2000
The photocycle of pharaonis halorhodopsin was investigated in the presence of 100mM NaN3 and 1M Na2SO4. Recent observations established that the replacement of the chloride ion with azide transforms the photocycle from a chloride-transporting one into a ...

Proton pumping activity and photocycle kinetics.

, 2014
(a) Light induced proton fluxes in E. coli vesicles containing wild type and mutant GR. Initial pH values were adjusted to7. The buffering capacity was calibrated and the pH changes were recalculated into proton concentrations. (b) Photocycle kinetics of
