Active Membrane Fluctuations Studied by Micropipet Aspiration [PDF]

, 2001
We present a detailed analysis of the micropipet experiments recently reported in J-B. Manneville et al., Phys. Rev. Lett. 82, 4356--4359 (1999), including a derivation of the expected behaviour of the membrane tension as a function of the areal strain ...

Preparation of Neurospora crassa mitochondria [PDF]

, 1978
The fungus Neurospora crassa represents a eukaryotic cell with high biosynthetic activities. Cell mass doubles in 2-4 hr during expone ntial growth , even in simple salt media with sucrose as the sole carbon source. The microorgani sm forms a mycelium of

Engineering and Production of the Light-Driven Proton Pump Bacteriorhodopsin in 2D Crystals for Basic Research and Applied Technologies

Methods and Protocols, 2020
The light-driven proton pump bacteriorhodopsin (BR) from the extreme halophilic archaeon Halobacterium salinarum is a retinal-binding protein, which forms highly ordered and thermally stable 2D crystals in native membranes (termed purple membranes).

The bacteriorhodopsin gene. [PDF]

Proceedings of the National Academy of Sciences, 1981
The bacteriorhodopsin gene has been identified in a 5.3-kilobase restriction endonuclease fragment isolated from Halobacterium halobium DNA, using a cloned cDNA fragment as the probe. Of the 1229 nucleotides whose sequence was determined in the genomic fragment, 786 correspond to the structural gene of bacteriorhodopsin, 360 are upstream from the ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

The role of topology in electrical properties of bacteriorhodopsin and rat olfactory receptor I7

, 2010
We report on electrical properties of the two sensing proteins: bacteriorhodopsin and rat olfactory receptor OR-I7. As relevant transport parameters we consider the small-signal impedance spectrum and the static current-voltage characteristics ...

Optical picosecond studies of bacteriorhodopsin containing a sterically fixed retinal [PDF]

, 1984
The photochemical behaviour of an analogous bacteriorhodopsin (9,12-Ph-BR) which contains the sterically fixed 9,12-phenylretinal has been investigated with picosecond spectroscopy. The following results have been obtained.

Es werde Licht! Licht als Antrieb und Regulator in synthetischen Zellen

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Zellen sind Systeme außerhalb des Gleichgewichts, die ihre Eigenschaften in Raum und Zeit regulieren. In biomimetischen synthetischen Zellen bietet Licht eine einzigartige Möglichkeit, Vorgänge räumlich und zeitlich anzutreiben und zu kontrollieren.
