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 ...

Photoisomerization detected in a fully wavelength‐tunable rhodopsin mimic system
Acta Crystallographica Section D, Volume 82, Issue 6, Page 664-671, June 2026.The mechanism of retinal photoswitching is illuminated in a designed rhodopsin mimic. Two mechanisms, a conventional cis–trans isomerization and an unprecedented `photodehydration', are observed at atomic resolution in single crystals.We describe the photoisomerization of the retinylidene protonated Schiff base in human retinol‐binding protein II ...

On the two forms of bacteriorhodopsin
FEBS Letters, 1994 In our previous work [(1993) FEBS Lett. 313, 248‐250; (1993) Biochem. Int. 30,461‐469] M‐intermediate formation of wild‐type bacteriorhodopsin was shown to involve two components differing in time constants (τ1 = 60–70 μs and τ2 = 220–250 μs), which were suggested to reflect two independent pathways of M‐intermediate formation.

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling
British Journal of Pharmacology, Volume 183, Issue 11, Page 2619-2633, June 2026.G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.

Journal of Molecular Recognition, Volume 39, Issue 3, May 2026.ABSTRACT Coronaviruses, among other membrane‐enveloped viruses, can remain infectious on surfaces in ambient air for days. Many bacteria and fungi also expose their plasma membranes to air environments. Key survival strategies in air include hydrophobic coatings to prevent water loss and waxy or silica‐based resistant cell walls.
