Journal ArticleDOI
The eubacterium Ectothiorhodospira halophila is negatively phototactic, with a wavelength dependence that fits the absorption spectrum of the photoactive yellow protein.
TL;DR: To the authors' knowledge, this is the first report of a true repellent response to light in a free-swimming eubacterium, since the blue light response in Escherichia coli and Salmonella typhimurium is unlikely to be a sensory process.
Journal ArticleDOI
Molecular mechanism of photosignaling by archaeal sensory rhodopsins
TL;DR: The SR-Htr signaling complexes allow studies of the biophysical chemistry of signal generation and relay, from the photobiophysics of initial excitation of the receptors to the final output at the level of the flagellar motor switch, revealing fundamental principles of sensory transduction.
Journal ArticleDOI
Thiol ester-linked p-coumaric acid as a new photoactive prosthetic group in a protein with rhodopsin-like photochemistry
Wouter D. Hoff,Petra Düx,Karl Hård,Bart Devreese,I. M. Nugteren-Roodzant,Wim Crielaard,Rolf Boelens,Robert Kaptein,J. Van Beeumen,Klaas J. Hellingwerf +9 more
TL;DR: PYP is the first example of a protein containing p-coumaric acid, a metabolite previously found only in plants, as a prosthetic group and establishes the photoactive yellow proteins as a new type of photochemically active receptor molecule.
Journal ArticleDOI
Measurement and global analysis of the absorbance changes in the photocycle of the photoactive yellow protein from Ectothiorhodospira halophila
Wouter D. Hoff,I.H.M. van Stokkum,H.J. van Ramesdonk,M. E. van Brederode,Albert M. Brouwer,J. C. Fitch,Terry E. Meyer,R. van Grondelle,Klaas J. Hellingwerf +8 more
TL;DR: Global analysis of the data established that in the time domain between 5 ns and 2 s only two intermediates are involved in the room temperature photocycle of PYP, as has been proposed before.
Journal ArticleDOI
Evidence for trans-cis isomerization of the p-coumaric acid chromophore as the photochemical basis of the photocycle of photoactive yellow protein
TL;DR: The data presented here establish the photo‐isomerization of the vinyl double bond in the chromophore yellow protein, a eubacterial photosensory protein, offering an explanation for the strong spectroscopic similarities between photoactive yellow protein and the sensory rhodopsins.
