Phytochrome proteins control the growth, reproduction, and photosynthesis of plants, fungi, and bacteria. Light is detected by a bilin cofactor, but it remains elusive how this leads to activation of the protein through structural changes. We present

The bacteriophytochrome DrBphP from Deinococcus radiodurans shows high sequence homology to the histidine kinase Agp1 from Agrobacterium fabrum but lacks kinase activity. Here, the authors structurally and biochemically analyse DrBphP and Agp1, showi

Sensor histidine kinases (SHK) consist of sensor, linker and kinase modules and different models for SHK signal transduction have been proposed. Here the authors present nano- to millisecond time-resolved X-ray scattering measurements, which reveal a

In addition to oxygenic photosynthetic systems, solar radiation is utilized for energy by diverse anoxygenic photosynthetic systems. Aerobic anoxygenic phototrophic bacteria (AAPB) perform photosynthesis without producing oxygen but still live in aer

Remote sensing methods enable detection of solar-induced chlorophyll a fluorescence. However, to unleash the full potential of this signal, intensive cross-disciplinary work is required to harmonize biophysical and ecophysiological studies. For decad

Signal propagation in photosensory proteins is a complex and multidimensional event. Unraveling such mechanisms site-specifically in real time is an eligible but a challenging goal. Here, we elucidate the site-specific events in a red-light sensing p

Signal transduction typically starts with either ligand binding or cofactor activation, eventually affecting biological activities in the cell. In red light-sensing phytochromes, isomerization of the bilin chromophore results in regulation of the act
