New atom-scale knowledge on the function of biological photosensors
Date:5/2/2014

rome structures were clarified both in a crystal form and in a solution. From the crystal structures, it is possible to see that small movement of individual atoms (scale of 0.1 0.2 nm) caused by the absorption of light is amplified to large structural changes (3 nanometres) in the whole protein complex. This amplification mechanism enables the light induced signal transmission from one protein to another very quickly and with precise replication accuracy. In turn, this signal transmission process initiates cellular-level changes in the organism.
