Confinement in crystal lattice alters entire photocycle pathway of the Photoactive Yellow Protein.
Patrick E. Konold,Enis Arik,Jörn Weißenborn,Jos C. Arents,Klaas J. Hellingwerf,Ivo H. M. van Stokkum,John T. M. Kennis,Marie Louise Groot +7 more
TL;DR: It is found that the photocycle kinetics and structural intermediates of PYP deviate in the crystalline state, which must be taken into consideration when planning TRC experiments, illustrates that ultrafast TRC results cannot be uncritically extrapolated to in vivo function and that comparative spectroscopic experiments on proteins in crystalline and solution states can help identify structural intermediate under native conditions.

TL;DR: This work reports the complete excited- and ground-state dynamics of the UV form of histidine kinase rhodopsin 1 (HKR1) from eukaryotic algae, using femtosecond stimulated Raman spectroscopy (FSRS) and transient absorption spectroscopic, and found that energy-level ordering is inverted with respect to visible-absorbing r Rhodopsins.

TL;DR: In this paper, the authors presented a methodology that provides a complete parametric description of the time evolution of the electronically and vibrationally excited states as detected by ultrafast transient absorption (TA).

Spectral watermarking in femtosecond stimulated Raman spectroscopy: resolving the nature of the carotenoid S* state.
TL;DR: A new method for recording femtosecond stimulated Raman spectra was developed that dramatically improves and automatizes baseline problems and delivered improvement in FSRS experiments, demonstrating evidence that the so-called S* state of carotenoids in solution corresponds to the optically forbidden S1 state of a sparsely populatedCarotenoid conformation.
