▪ Abstract Time-resolved infrared (IR) and Raman spectroscopy elucidates molecular
structure evolution during ultrafast chemical reactions. Following vibrational marker modes …

Only five major types of sensory photoreceptors (BLUF-proteins, cryptochromes,
phototropins, phytochromes, and rhodopsins) are used in nature to regulate developmental …

A variety of organisms have evolved mechanisms to detect and respond to light, in which the
response is mediated by protein structural changes after photon absorption. The initial step …

To understand how signaling proteins function, it is crucial to know the time-ordered
sequence of events that lead to the signaling state. We recently developed on the BioCARS …

Trans-to-cis isomerization, the key reaction in photoactive proteins, usually cannot occur
through the standard one-bond-flip mechanism. Owing to spatial constraints imposed by a …

In the chlorophyll biosynthetic pathway, the enzyme protochlorophyllide oxidoreductase
(POR) catalyses a key light-driven reaction that triggers a profound transformation in plant …

Unveiling the nuclear motions of photoreceptor proteins in action is a crucial goal in protein
science in order to understand their elaborate mechanisms and how they achieve optimal …

The first stage in biological signaling is based on changes in the functional state of a
receptor protein triggered by interaction of the receptor with its ligand (s). The light-triggered …

Photoactive yellow protein is the protein responsible for initiating the" blue-light vision" of
Halorhodospira halophila. The dynamical processes responsible for triggering the …

The cyanobacterial water-soluble orange carotenoid binding protein (OCP) is an ideal
system for study of the effects of protein environment on photophysical properties of …
