The photochemical reaction dynamics of YcgF, a BLUF protein, were investigated by the pulsed laser-induced transient grating (TG) technique. The TG signal showed three reaction time constants: 2.7 micros, 13 micros, and 2 ms. The fastest was tentatively attributed to relaxation of the excited triplet state of the chromophore, flavin adenine dinucleotide (FAD), and the others represented conformational changes of the protein. The TG signal provided clear evidence that the diffusion coefficient… Expand
Oligomeric-state-dependent conformational change of the BLUF protein TePixD (Tll0078).
The photochemical reaction dynamics of a BLUF (sensors of blue light using FAD) protein, PixD, from a thermophilic cyanobacterium Thermosynechococcus elongatus BP-1 (TePixD, Tll0078) were studied by pulsed laser-induced transient grating method and demonstrated that only the decamer state is responsible for the conformational change.

Conformational and Intermolecular Interaction Dynamics of Photolyase/Cryptochrome Proteins Monitored by the Time‐Resolved Diffusion Technique
Cryptochrome (CRY), a blue light sensor protein, possesses a similar domain structure to photolyase (PHR) that, upon absorption of light, repairs DNA damage, which indicates that the protein–solvent interaction is changed by the conformational change. Expand
Photoreaction of BlrP1: the role of a nonlinear photo-intensity sensor.
The results suggest that BlrP1 is not only a photosensor but also a light intensity sensor possessing a nonlinear response. Expand
Dynamics of Conformational Changes in Full-Length Phytochrome from Cyanobacterium Synechocystis sp. PCC6803 (Cph1) Monitored by Time-Resolved Translational Diffusion Detection.
It was found that the kinetics of the HK domain movement of the Cph1 dimer could be monitored successfully and the fact that the rate is similar to that from the transient absorption method suggests that the proton uptake at His260 is the rate-determining step of the conformational change. Expand
Photo-induced inter-protein interaction changes in the time domain; a blue light sensor protein PixD
ABSTRACT : For understanding molecular mechanisms of photochemical reactions, in particular reactions of proteins with biological functions, it is important to elucidate both the initial reactionsExpand
Charge stabilization in reaction center protein investigated by optical heterodyne detected transient grating spectroscopy
The conformation change of RCs was investigated using heterodyne detection of the laser-induced transient grating method and the decay component was found at few hundreds of microseconds time scale indicating that there is no large displacement in the RC structure if QB is present. Expand
Protein conformational dynamics of homodimeric hemoglobin revealed by combined time-resolved spectroscopic probes.
The results show that the combination of complementary probes allows a more convincing and comprehensive assignment of the observed timescales to tertiary and quaternary structural transitions and corrects some of previous kinetic assignments, underscoring the importance of employing combined probes.

Revealing the Functional States in the Active Site of BLUF Photoreceptors from Electrochromic Shift Calculations
A keto–enol tautomerization of the glutamine at position 63, which was proposed as molecular mechanism for the transition between the dark and the light-adapted state, explains the measured 10 to 15 nm red shift in flavin absorption between these two states of the protein. Expand
Illuminating solution responses of a LOV domain protein with photocoupled small-angle X-ray scattering.
The PAS-LOV domain is a signal-transducing component found in a large variety of proteins that is responsible for sensing different stimuli such as light, oxygen, and voltage and a reaction scheme is described that describes the mechanism for light-induced dimerization of VVD. Expand
Light-induced conformational changes in full-length Arabidopsis thaliana cryptochrome.
It is concluded that the observed large conformational changes triggered by light excitation of the PHR-like domain result from C-terminal domain rearrangement, which would be critical for CRYs' ability to transduce a blue-light signal into altered protein-protein interactions for biological activity.
