Owing to its ubiquity and easy availability in nature, light has been widely employed to
control complex cellular behaviors. Light-sensitive proteins are the foundation to such …

Horticultural greenhouse production in circumpolar regions (> 60° N latitude), but also at
lower latitudes, is dependent on artificial assimilation lighting to improve plant performance …

Protein–protein interactions (PPIs) can be detected through selective complementation of
split fluorescent reporters made of two complementary fragments that reassemble into a …

We have used transient absorption spectroscopy in the UV–visible and X-ray regions to
characterize the excited state of CarH, a protein photoreceptor that uses a form of B12 …

Light-induced difference Fourier-transform infrared (FTIR) spectroscopy is a powerful,
sensitive and informative method for studying protein structural changes in photoreceptive …

The Ectothiorhodospiraceae family represents purple sulfur bacteria of the
Gammaproteobacteria found primarily in alkaline soda lakes of moderate to extremely high …

Photoactive yellow protein (PYP) is a model photoreceptor. It binds ap-coumaric acid as a
chromophore, thus enabling blue light sensing. The first discovered single-domain PYP from …

Nature provides an array of proteins that change conformation in response to light. The
discovery of a complementary array of proteins that bind only the light-state or dark-state …

In recent years it has become increasingly evident that prokaryotic organisms can sense and
react to light stimuli via a variety of photosensory receptors and signal transduction …

Upon blue light irradiation, photoactive yellow protein (PYP) undergoes a conformational
change that involves large movements at the N-terminus of the protein. We reasoned that …
