Light‐Based Molecular Tools to Precisely Monitor and Operate β‐Adrenoceptors
Medicinal Research Reviews, Volume 46, Issue 2, Page 445-474, March 2026.ABSTRACT β‐Adrenoceptors are important G protein–coupled receptors involved in cardiovascular, metabolic, and neurological regulation. To study their function with high precision, light‐based molecular tools have been developed offering precise spatiotemporal control.

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 ...

Verbesserte Auflösung in der ESR‐Spektroskopie unter Verwendung von para‐Wasserstoff‐Matrizen
Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.Wir demonstrieren die vorteilhaften Eigenschaften von festen para‐Wasserstoff (p‐H2)‐Matrizen für die Elektronenspinresonanz (ESR) Spektroskopie, indem wir das 2,2,6,6‐Tetramethylpiperidinyloxyl (TEMPO)‐Radikal und ein in situ erzeugtes P‐zentriertes Monoradikal untersuchen. Die spektrale Auflösung des P‐zentrierten Radikals in p‐H2 ist im Vergleich zu

Biomolecular imaging and electronic damage using X-ray free-electron lasers
, 2010 Proposals to determine biomolecular structures from diffraction experiments using femtosecond X-ray free-electron laser (XFEL) pulses involve a conflict between the incident brightness required to achieve diffraction-limited atomic resolution and the ...

Photochemical reaction of bacteriorhodopsin
FEBS Letters, 1976 Halobacterium halobium utilizes light both as a stimulus for phototaxis [l] and as an energy source for creating a proton gradient across the cell membrane which in turn produces ATP [2] . The photoreceptive pigment of this bacterium was first investigated by Oesterhelt and Stoeckenius [3] who showed that it is the only protein lying in so-called ...
